- 2007 2008 2009 2010 Toyota Sienna 3.5 V6 2GR-FE Lexus 3.5. How to replace Transmission speed sensor. How to fix code P0793.
Faulty sensor also triggers traction and stability control lights if equipped.
part may be related to P0791 P0792 P0794, see video for detail.
Video may apply also to other Toyota and Lexus models.
OEM TOYOTA part # 89413-48010.
I just followed your instructions this afternoon (7/6/2024) on my 07 Sienna and was able to change my speed sensor within 30 minutes. What took me the longest was trying to take out some old rusted screws that were holding on to the air filter clamp for dear life, lol. The original sensor was a little tough to take out to but with a little twisting and turning, it finally came out. Once those screws and original sensor came out, the new sensor was installed easily and it was really easy to put it all back together again. Thank you for recording this video for the general population. You saved me a few hundred dollars!
Thanks for the feedback. It's been around 4 years and I still have the van with no transmission issues at all after this repair.
This is how you do a repair video, perfect. Thank you for taking the time to do this, all the info and the time to upload. Your effort is appreciated!
I watched this, purchased the part and fixed my van! Thank you Sir!
Thanks for the feedback.
Thank you for sharing your fix. I am now more hopeful about my repair job.
Very detailed, thank you. I feel nervous about doing it, but I want to try doing it myself. The Toyota part costs $106, the transmission repair shop I talked to quoted $375 for parts and labor. But the worst part is they dont offer any guarantee or warranty for their work. That makes me hesitant to pay 375 for work with no guarantee. So, I will try to do it myself. :)
If you know how to replace a battery and air filter, and you have the tool, you are good to go. Having a WD-40 is a plus. Just make sure you check the wires, and you have the right diagnostic. And again, use an oem part from Toyota dealer, aftermarket is not going to save you any money and it's not going to work.
And remember to take pictures for the suction houses attached to the air filter box, so you know which one goes where.
@@PickyOne Taking picture is a great idea. The code I got for CEL is P0793. I haven't replaced a battery before, only replaced a headlight bulb, and changed the cabin air filter. A little nervous, but it's such a difficulty to find a trustworthy auto mechanic. The transmission shop owner said he will check the wiring, but he didn't actually check any wiring, just visually looked at it and read the code, and then told me to replace the transmission speed sensor.
@@PickyOne Indeed, that suction house part made me feel nervous when seeing it in the video. 🤠
2010 Toyota Camry car jerks when accelerating from a stop
Thanks for the detailed instructions. I replaced sensor and it resolved the P0793 code but left a P2714 code and still having the same symptoms as before, jerky gear shift and significant vibration. Any input on next steps would be appreciated. Leaning toward taking it into the shop. Update: Replaced 4 year old battery and resolved the issue.
P2714 is very broad. Hard to find a video on a Sienna for the same problem. Try Toyota Nation website but you can start with this video just to get an idea.

Most likely due to the computer relearning the new sensor, resetting the battery initiates that too.
Great video and better then all others. Very clear thanks
Thanks
Thanks for the video..
FYI.. Next time use a silicone based lubricant/grease, WD40 degrades rubbers & plastics.
That's true, but I sprayed the old part only which was going to the trash. The new part comes with a new O ring, and I cleaned before installing. Thanks for the comment.
Your video was super helpful, not only did I get the wrong part for the trouble code I was having, i put it in the wrong place .. so by you calling out each sensor and it's color fix all my problems. So the part I got was for this code.. but I had originally got the other code.. so I'm assuming if you get the first code it doesn't always mean it couldn't be the second sensor
does it work on 2015 sienna?
How about the 2015 Highlander Limited 3.5L V6 Intermediate Shaft Speed A. Circuit. Toyota Part Number and location??
I got the same issue, but my car is 2015 Toyota sienna, is it the same solution?
Thanks for the video! I have a 2007 Toyota Sienna LE. Can you tell my which number this sensor is? The Toyota website asks if it's 1 or 2?
I believe it's #1 .
I remember coming across this question 4 years ago when I did the repair. I had to consult an out-of-state mechanic over the phone, and he just told me to go with the blue one, not the black one. By the way, I still own the van and never had a problem with the transmission after that.
I can't find the speed sensor on a sienna 2014. can you help me? and it's different
Hi, also, do you know how some people could do it without removing the air box? Did they remove the battery instead, or did they just reach the hand down? Thank you for your great, detailed video.
I've seen a video for a guy who didn't remove the box but he removed the battery and reached the part with a long tool. I didn't like the idea since it's risky and could damage the plug.
You can remove the battery and the box bottom and filter but keep the box top hat attached to the hoses.
After replacing the part do I have to drive it like 20-50 miles? Or it alright fixed the issue.
Hi what is about the 2014 Sienna is it the same sensor?
@@tbktuvshin7972 generally the same process, but check for the part number since the 2014 has an updated transmission. Better to check either Toyota Nation or Sienna Chat websites.
Hello, is this the same as the intermediate speed shaft sensor for the toyota highlander 2013?
The short answer is : " I don't know". I'm not a professional Toyota mechanic, and the Highlander is a different story since most of models sold are AWD and the van shown here is FWD despite having the same engine. I highly recommend checking Toyota Nation forum as step one to get more specific information about your Highlander. Don't start the repair based on trail and error. Thanks for watching.
Hi, do you think it will be ok to turn on the engine briefly after installing the new sensor, before installing air box and duct back in place, just to see if the check engine light will go away with the new sensor? Or that's not going to work if air box and duct aren't back in place?
It's a bad idea to start the engine without a filter. If you reach to the point that the problem is blue sensor and your replaced it with a new one, your problem is solved. The engine light is a secondary issue and it will go away or you can erase it with a code reader, even without replacing the part.
@@PickyOne Thanks. That makes sense. I just got the sensor part from Toyota and am trying to get the tools for it. Could you tell me are all of these bolts hex nuts or 12 facet nuts? It seems the tool i am looking at, for hex nuts, only goes up to 9mm. From 10, 12, to 19mm, it says 12 Pt. Skts.
@@brighteyes6559 the sockets I used in the video have six sided interior. The 12-sided will work. I'm not sure if they still sell 12-sided for smaller sockets, but as far as it says MM you're good to go.
@@PickyOne I see. I managed to find 6 sided sockets of 10 and 12mm. I can work on the car tomorrow. Really excited about this. Will let you know how it went :)
I didn't know 12 sided sockets work on 6 sided bolts, too. That's cool to know!
@@PickyOneHi, I tried to remove the air filter box, but I was too nervous about disconnecting the air duct pipes, etc, so I didn't continue. I know it's totally doable. I just didn't have enough experience to feel confident about it. 🙂
So I hired a car mechanic who is installing it for me right now. Could you tell me should I ask him to reset the check engine light after installation and observe if it comes back, or the check engine light should go away naturally by itself (right after installation) without resetting? Thank you so much.
Hi. I need to replace my speed sensor. The red and white wiring of the socket got chewed off. Do you have another video on how replacing the socket? Thanks
I have another video but not for this 2-wire socket, it's for a 3-wire socket. Watching my other long video can give you an idea of how to search for an aftermarket socket/wires kit. You may NOT need to replace the sensor if you fix the socket, but if you need to replace it, never ever go aftermarket (go OEM only). For for the socket, you can go aftermarket. Sorry for the redundancy, here's the link:
th-cam.com/video/JoS28JFa9A4/w-d-xo.html
@@PickyOne thank you for the video. It will be a challenge connecting those 2 wires.
@@jd061010 some professional mechanics said I need to solder the wires, but it was almost impossible at that location. So, I used a heat shrink butt connectors (As shown on that video) and so far no problems, it's been a year now and 20 K miles.
Yesterday someone called me to fix is car problem. Which is exactly what you are doing here. I never knew the location of that tfp solenoid.
The problem of the car was after the customer added oil to the gear because it was low the car didn't go into reverse gear anymore but drives forward only.
But when I plugged in my scan tool to the car these codes appeared: Car Scanner ELM OBD2

The check engine light also came up which I cleared but it came back again. I repeated this procedure trice but the light came back in every try. I checked the fuses and relays everything was ok. Please what should I do now. Help me. The connectors how many earth, ignition and power are there?
Just wondering what were the other 2 codes that were triggered and then disappeared when you replaced the original code part?
I may have misspoken it. What I meant was whenever you get this OBD code, you will automatically get two other lights, the traction control light and stability control light, I may have called them codes but actually they're not they're only warning lights. Every time you have a transmission related OBD code the features of stability control and traction control are automatically turned off. Whenever you fix the problem that triggered the code, all other related lights will shut off and everything will go back to normal.
@@PickyOne Thanks. I received 2 codes; the P0793 and P2714 the pressure control solenoid D.
I haven't experienced the other code the solenoid code, sorry I have no knowledge of that.
@@PickyOne Just an update that I had originally replaced the sensor with a cheaper ($50) aftermarket version and received new codes and the shifting issues continued.
I then bought the genuine Toyota sensor for $97 bucks and it cleared ALL codes and fixed the shifting issues.
@@shotojukukai I'm happy to hear that. I read on Toyota Nation forum the same that after-market part does not solve the issue and in some cases it's more expensive than the OEM!
Hi, when you bought this part, did it come with the O ring, or did you have to order it yourself?
It came with the rubber ring attached around it as one piece.
@@PickyOne Oh, that's great to hear. So i can just spray some wd40 on it, and push the sensor in :)
I had a few codes ABS and VSS vehicles speed sensor like you.
What scanner are you using i bought a Zurich (ZR8) but its says"this tool does not support ABS for this vehicle "( 2006 Toyota sienna CE) i already changed the VSS sensors...
The red device I used in this video is just a basic code reader and engine light eraser, that's the most basic device available, it can't be called a scanner, it does not fix ABS brakes issues or SRS airbag problems. To the limit of my knowledge some abs issues needs a two-way scanner.
My Sienna started bogging down really bad when I start to accelerate, but the engine revs up fine when I am in Park. Is this a symptom of a bad speed sensor or something else? I don't have any error codes as of yet. Thank you.
I really need help with this. Toyota Sienna 06, Judy changed both sensors , took two hours . Check engine gone but shifts like crap, no speedometer reading or cruise. Ideas what I should do. ! I bought 110 sensor on from ngk. I decided while I’m there to replace both. The black they say input and greenish ones was output. If I’m wrong there them I bought wrong sensors , please help
The problem should be in your cluster it’s all connected you probably need a new cluster
Great video brother! I have the same issue.. I got the new VSS from Toyota and installed it.. all the wires checked out ok.. the problem is still acting up.. should I clear the computer?
If have the code reader, you can clear the code. In my case the code was automatically cleared since the battery was disconnected the whole repair time. My van acted once after the repair but it went normal again, may be the transmission was in the relearn phase, as you may know , there is a simple computer that runs the show and in rare cases dealers reflash the software. Since I uploaded the video, my van is running smooth and shift like new.
Hi! excellent video! I got the P0793, i checked resistance value but it's 650 ohms which is a god one value, anyway I replaced with an after market part but code still present. If resistance value is ok, is it advisable to buy original part from Toyota? or it could be another component failure?
Theoretically, the first thing to do is to visually check the harness (the wires), it's a sweet spot for rodents in winter time. If wires look ok, check the resistance for both the sensor and the wires, I don't have the numbers handy. In general, it's the sensor that goes bad even if it gives you numbers within the range, for some reason the computer won't accept it. Numerous posts by Sienna owners mentioned that aftermarket part did not solve the problem and they have to switch to Toyota oem part. In my case, I started the work on a Saturday morning and rushed to the dealer to get the part before they close. My local AutoZone was offering an aftermarket part for the same price. I didn't have time for trial and error I've just installed the new oem part as shown and problems are gone.
Question... So I'm getting the same code and got to the sensor. Previously someone mentioned that a good sensor will have a continuity of 650 ohms. The one on my vehicle shows no continuity / open. I just want to confirm that this is definitely a bad sensor.
Hi,
I have 08 Toyota Highlander v6 automatic and got a code P0717 input shaft speed sensor. I got check engine and traction lights are on and vehicle won’t shift normally like jerking. I replace the blue sensor the same one showing on the video and is aftermarket one and lights came on after 30 miles driving. I already check the wiring and looks like nothing abnormal. Any advice for this issue?
Thank you
the code you got P0717 is not necessarily related to this specific blue sensor, despite having the same symptoms. maybe you didn't have a problem with the sensor in the first place.
So what is the code for the one on the side??
I'm getting P0500 Vehicle speed malfunction error. Is this the same problem with the P0793? My car is Lexus es350 with the same 3.5 V6 2GR-FE Engine. Someone explain please. Thanks
Hd had a blowout not shifting right and no speedometer
Hi. Thanks for the video. I tested the resistance and it’s in range however the wires were cut by rats. I fixed the wires but the track and VSC lights are still on. How long does it take for the code to reset. Thanks
If you have an OBD2 scanner, you can erase the code and the other lights ( traction/VSC) will disappear automatically with it. If you don't have a scanner, try disconnecting the battery terminal for 15 minutes. There's a possibility that the chewed wires cause some harm to the sensor itself but I'm not sure, I assume you did not replace the sensor. Some old sensors will give you good numbers while testing but they act up in real life. Also you can check the resistance of the harness itself, I don't have the exact numbers handy.

What is the symptoms for this when it happened?
I want to do preventive maintenance and curious.
There's no preventive maintenance for this part, if it's not broken don't fix it.
If this part stops sending the required info, the transmission will start acting up and not shifting on time, and the VSC (vehicle stability control) and TRAC (traction control) features will be disabled.
@@PickyOne I see. Good to know. Thanks you sir
I have a 11 es 350 the sensor is not in tht location
My amigo. Como se llma el cable k entra en el sensor..el mio se ronpio... el k dises el sakeddddd....
If your cable is damaged you can buy an after-market socket with wires for Toyota transmission speed sensor from Amazon. Just like I did with my VVTi sensor video but the socket is slightly different. th-cam.com/video/JoS28JFa9A4/w-d-xo.html
Hi, I have a toyota Sienna 2008 .
I have a code p0717 .
I have been changed the transmission speed sensor which is under Air filter box but have same transmission problem .please guide me . t.v. thanks
The blue sensor under the air filter box (shown in this video) is not related to the code you mentioned.
Please check the other sensor (black) and the wires prior to replacement.
Always replace those sensors with OEM from a Toyota dealer. After market sensors are not good at all and not cheap anyway.
The blue and the black sensors are not interchangeable and you can't use one in the place of the other.
Always check the wires prior any replacement. The sensors are located in a spot that's very attractive to rodents in winter time.
