Hi, do you know if 1999 mazda astina 323 bj 1.6 fluid pressure sensor is external or internal? And where abouts its located? Thanks
I have a Mazda 6 2009 having this issue it’s throwing the same code would you suggest I fix the sensor then a transmission flush?
I would just recommend the sensor honestly. Sensors, like all electronics, fail over time. Ive never had any of my transmissions flushed, nor ever plan to. I have heard horror stories of new issues arising afterwards. Best of luck! Dont fodget to subscribe!
Hey, I’m assuming this wouldn’t be the same process on the 2013 Mazda 3? (5 speed auto transmission)
Hello. If you have the same engine code odds are you have the same issue. The only difference is your sensor is likely to be in a different location on the transmission.
Hey is the transmission fluid pressure sensor for a 2016 mazda 6 grand touring Inside (internal) or outside (external) the transmission . Cant seem to find the right answer. Thanks
Looks like its more on the bottom.
@@blueglovemechanicshould I take the dealers service word. On it "could be" more than the tranny fluid sensor . And get a second opinion? The Tranny Fluid sensor was confirmed to be bad. Thanks
I have the same problem on my 2015 outback will replacing the sensor fix my issue hopefully?
@@carllemke4622 Ideally it will help resolve the issue causing your check engine light (and should be your cheapest option/first step). However, there could be different causes for the issue as well (such as TCM being bad). What symptoms are you experiencing?
@@blueglovemechanic so there was no check engine light but coming up the hill it felt like it was jerking back-and-forth slightly, which it never does so I decided to scan it and the code P0841 came up related to transmission fluid pressure sensor circuit malfunction that’s why I’m hoping changing the pressure sensor circuit switchwill help rectify the situation
@@carllemke4622did it fix the problem??
Hi, I have a question for you. Is the location of the gearbox oil pressure sensor different in different cars? My car gives the same error code, but they tell me that the problem may come from other parts of the gearbox
Hey there. Yes, the sensor may be located elsewhere on the transmission, but should be in the general area. If you google your cars year, make, model and include the words "transmission fluid pressure sensor location" you should be able to look at google images and get a general idea on the location. Best of luck!
I have a question, is it necessary to disconnect the battery to do the replacement of this sensor? Or is nos necessary?
No battery disconnect necessary. Just pop the sensor loose and unscrew.
Hello sir, I have the same model of vehicle, that I scan it gives me the same code can you please tell me what are the things you noticed before changing this part. And also after changing it what you noticed. Thanks 😊 your response is very valuable to me
Hello. The car did have some hesitant/delayed shifting and i could only read the code by scanning the tcm via my more expensive scan tool (it didnt throw the check engine light strange enough). After changing the sensor and driving the vehicle around 100 miles the transmission code never came back. I do however still have a minor poor acceleration/poor gas mileage/lack of power issue which i believe is being caused by a clogged catalytic converter. I replaced both oxygen sensors and got an engine running lean code. I pulled my fuel pump and found the filter is quite dirty so ill be replacing that to rule out fuel issues. I pulled fuel rail and turned car over to ensure injectors are not clogged as well. I already pulled the cats and was able to see through them but believe they are probably clogged to the point where the issues are moderate. What issues are you currently experiencing?
@@blueglovemechanic what fixed yours?
Hello, I followed your instructions and installed the new sensor, but it is still throwing the same code, any ideas for why it may be doing this? I have a 2010 Mazda 3
Hey there. Sorry to hear it didnt work. Have you confirmed your transmission fluid level is correct?
Hello friend, I have the same problem on my 2010 Mazda 3. I must change this sensor. My question is, is it located the same as in this video?
Does anybody know where the 2004 dodge intrepid se transmission fluid pressure sensors located?
Hello. I am looking for a connector for this product. Where can I find it. I couldn’t find it. Does anyone have any information? Thank you in advance.
@@aliesadaygun hey there. Are you looking for the plug on the end of the wire?
@@blueglovemechanic Hello. Yes. I’m looking for the plug that goes into the sensor.
@@aliesadaygun Should be this one :
amzn.to/3YTB4Oh
I know it might not say it fits certain vehicles but its just a connector with a single wire. Unsure if you have the original to compare to the photos but i believe this one should work. Best of luck!
@@blueglovemechanic Are you sure this is true? Is the same product used for the engine and transmission?
@@aliesadaygun generally plugs are quite universal. If you go to a local car parts store they sell "pig tail connectors" which can be used for multiple functions. As long as the plug connects to your sensor and the cable is wired correctly you should be good.
Hola ese sensor le cae al mazda 6 2005 o son diferentes
Hola, el código de verificación del motor es técnicamente universal, por lo que debería ser el mismo sensor el que causa el problema; sin embargo, podría estar en una ubicación diferente de la transmisión. Necesitará buscar un diagrama para encontrar la ubicación. ¡toda la suerte!
Gracias bro, es que mi carro no coje los cambios, osea la transmisión patina y me sale ese código debería ser ese sensor y listo creo cierto
Got the code on my mazda, but it lost power, only cranks with a nasty metal on metal sound. Will no longer start/run.
@@AbeVicious yikes, sounds like youve got a more serious engine problem to me unfortunately. Might have had rod knock and now seized your engine. Best of luck.
@blueglovemechanic yea not sure. I am getting p0841 and p0303
Did you experience any issues when you got this code? If so, let us know what they were!
Hi, I have a vw mk 7 golf 1.6 disel and have the same fault code and its causing my gearbox to over rev tru the gears when driving. Did the car in the video experience the same with that fault code. Will my fix mostlikley be the pressure sensor ?
@@MR-hj9db hey there. My symptoms were moderate but the sensor is definitely where i would start. Its a cheap quick fix and will get you started on the right path as a faulty/failing sensor will send incorrect signals to the TCM so your transmission will most likely have shifting issues. Worse case scenario would be internal transmission failure. Best of luck with your repair and please let us know what you find!
Ese sensor también lo trae el nissan sentra 2008
