Top tip: hot glue works really good at insulating the electrical connections. I make one that is adjustable from 0-500 ohms, on both the signal and the heater circuit. Why do you need a capacitor?
Hey this does work on that truck using the resistor and capacitor you were using. But you need to know that the capicitor has a directional polarity. It needs to be connected with the leads going in a certain direction my friend. side of the capicitor with the black band is the negative side and current can only go from positive to negative through the capicitor so the side with the black band needs to connect to the resistor and the positive side of the capicitor needs to connect to the black wire.
Not exactly a capacotor swot hes the ditections of the current at contanuity from begging up to capacitance fown to zero cap then the polarity switches to do it again the other direction until it teaches capacitance to reverse again so you may wamt to rethi k your lack of knowledge on how electricle coponents work
th-cam.com/users/shorts9P-3uosHXOw?si=skr-zmbGCBguadNm I tried resisters diaoides ect nothing worked for me but this way did I actually did it today and was shocked to see it working lol..On a 04 5.7 ram..U can actually see your light plusing with the signal..
It did work the heater circuit is a bad o2 or broken wire you gotta start with a good o2 your mod only accounts for the exhaust signal the ecm reads (no cat fix) but not a sensor defect
You don't even need to plug it back into your 02 sensor as long as you use 2 of 1 Ohm 1/4 watt resistors I have 4 wires on mine 2 white wires and 1 Grey and 1 Black wire, I put 1 resistor between the 2 White Wires and then put the other Resistor between the Grey and Black wire then heat Shrink those the Black and Grey with the resistor on it, and did the same to the other 2 white wires, No-more Check Engine light all you needs left to do is just plug it right into the o2 sensor main Harness. then you're done. I cut off the Connectors from the 02 oxygen sensors. ( Note: that the sensors are still bolted on the pipe ). I have noticed a big difference in my Horsepower before it was sluggish before but now what a difference.
I know this is old, but if you are getting a code for the heater, you either have a bad heater in the 02 sensor or a bad wire going from the 02 sensor to the computer. The mod you did doesn't do anything to the 02 heater circuit, and it still requires that to work. I did this on my truck last year and it does work.
I changed the error reporting status on mine just to get rid of that glowing devil in my gauge cluster. Still running rich though.. Cool video bud. I have yet to find any diy sims that work, but at least yours showed the end result
if you fitted an adjustable voltage supply, you should be able to simulate the different readings the o2 sensor usually makes by making it's own voltage by changing your variable supply in place of the sensor wires (not the heating ones) You should be able to adjust the fuel richness at least. Or, just change the sensor or check the sensor's heater fuse didn't blow.
You have a vacuum leak. Smoke leak tester is the best way to find it, but who owns one? You can try propane, and it's way safer than spraying carb cleaner around a hot running engine. The rich condition is a response to lean feedback, or unmetered air in your A/F mixture. Good luck.
Yeah, the anti-Fowlers don’t work you’re lucky if you get two days out of it or a week but exactly 10 to 12,000 miles the light will come back on same code. You’ll have to deal with the issue you’ll have to fix it all it does is pull the O2 sensor away from the cat so it can read cleaner air. Yeah that was a total waste of time and money. It’s basically just to get you through emissions that’s all that’s all that’s for buying some time.
What you made is not an O2 simulator, it is a signal retarder. It smooths the signal, but the sensor is still required. A true simulator does not require you to have the second O2 sensors at all. You may want to correct the title of your video.
Not a whole lot you can do about the heater, that’s just because hotter gas is flowing through the exhaust and the sensor is picking up the hotter gas.
I didn't check how old this is but did you check the wires that are going to the sensor from the truck harness maybe the black wire in particular is damaged or something
The resister goes on the black wire. The capacitor goes after the resister towards the plug between the gray and the black wire. The Resister has to be 1mOhm and the capacitor 4.7 Also the it’s best to use a new O2 sensor.
Derek Sharon no I haven’t but I stopped driving it since I’m working on the solid axle, I’ll mess with it again after I get the truck driving , and if I figure it out I’ll make another video about it. Hope you get yours figured out.
Austin Koceja it looks like what you did didn't completely fail. I don't know much about this, I just started doing some research like you. I think the reason why you are still getting a code is because the O2 heater sensor (the two white wires) is not reading the right temperature. The post cast sensor should be reading hotter than the pre cat sensor since the exhaust gasses are heated as they pass through cat. Since you don't have a cat I think you need to trick the computer on the heater side of the O2 sensors as well. Maybe try doing what this guy did. th-cam.com/video/H6mX4efePx8/w-d-xo.html I don't know if it will work or not I'm just speculating. But if it does please let me know.
@@plumberpete86 ,I tried what the foreign guy did on my 141 fault and it didn't work. I'll put a new sensor in and it's bad a month later. I tried this with old sensors and a new one. Just worked for a month then done.

What's up cheaters, yeah I said it. 😮 So, it's, MHO that his mod worked, because the codes that didn't return are specifically for the O2 sensing circuits. There are four wires, or two circuits in his case. The other circuit is for the heater--the sensor will not report true readings until both it and the catalytic converters are hot, really hot!! The returning code only refers to the heater, not the sensor circuit, and I believe that the ECU doesn't require a drive cycle to report the heater issue. However, to be clear, he didn't complete a true drive cycle yet, and the ECU will not report until that is completed, so honestly I can't rightfully claim that the mod worked...but someone else reported that it did work. I believe that a simple cat delete would get good results with this mod. Unfortunately, I think if your vehicle has bad cats, and you are attempting to bypass them, then you will have negative results. It's my contention that whatever issue clogged up, burned out, or contaminated your cats will negate the otherwise positive outcome. 😢 The reality is that this mod is on the post-cat O2 sensor, and it's feedback is monitored by the ECU ( which is mandated by the EPA), and their way of overcoming cheat codes is to periodically have the ECU alter the Air/fuel ratio and it should see O2 sensor feedback that also varies...however, the added resistor/capacitor circuit can only create a steady response. The ECU sees this and throws a code--yup, your busted. Now, this isn't on all vehicles. To me it's a cheap and easy mod, so give it a try. 👍 Good luck...cheaters. 😅

With the spark plug fouler mod, put metal strings like from an SOS pad and it should work
On the downstream or upstream side?

Check the relays for the o2 heaters change them and do a diagnostic see if the heaters are turning on. Probably a sticking relay

Be sure you get the polarity of the capacitor right. It'll pop.
O2 heater malfunciton means your O2 sensor is bad and needs to be replaced. Nothing to do with exhaust gasses.

The technical term is an RC filter. You use a resistor and capacitor to filter out the signal.
any example of o2 simulator?
Does this work if I want to run wideband O2 sensors on LS stock ECU
@@mrtedco36 No, for that you actually need to make software changes in the ECU. I cannot say if HPTuners or a similar program can handle that.
Not a whole lot you can do about the heater, that’s just because hotter gas is flowing through the exhaust and the sensor is picking up the hotter gas.
Did u ever flip the cap to see if it work. I know that the cap. Has a 1 way flow u might of got it backward.
I didn't check how old this is but did you check the wires that are going to the sensor from the truck harness maybe the black wire in particular is damaged or something
No never did, the truck is motor swapped now so I never bothered with it agin
Check the relay switches for the o2 heaters 😎😎
All you need to do is just remove your ground wire off your battery
wait 2 minutes then reconnect it that is how i reset my light
That's you're upstream sensor..preheat. you need a new 1
Maybe add the spark plug defoulers with this mod and see haha
you supposed to cut the black, not the grey, use a ! Mega Ohm resistor, not a 1 ohm. The black is the signal wire.
I think he just expressed it improperly. A one ohm resistor is noticeably larger than what he had, which looked to be 1/4 watt.
Heater malfunction just get new o2 sensor. This mod wont fix. This is for no cats on car.
Think your resistor was not the right value, and maybe the heater part of sensor not working????
Supposed to be 1 meg ohm lol
The resister goes on the black wire. The capacitor goes after the resister towards the plug between the gray and the black wire. The Resister has to be 1mOhm and the capacitor 4.7
Also the it’s best to use a new O2 sensor.
It didn’t work because I believe the capacitor should be on the other side of the resistor. Will be doin this myself to confirm.
is it for o2senor 1 or for sensor 2 after the catyltic converter
After the cat
My token solutions o2 sim delete box stopped working how can I fix it? It might have shorted
can i use this circuit for malfunction sensor ?
Mumbler!

have you figured out why it gave you a different cel after the install? I'm having same issue. thanks!
