2020年5月28日 · I have been struggling with this fault code on my 2008 Audi S4. It comes on and off, mostly on. I have searched the forum and have seen some post/threads but no clear solution that have fixed my issue.

2009年3月25日 · Codes pulled were for P2138 Accelerator Position Sensor (G79/G185). I performed a TBA with Vagcom and the car has performed uneventfully until today. Same scenario, car was exposed to heavy rain overnight, and this afternoon my daughter reported the CEL EPC lights came on and the Tiptronic transmission wouldn't shift into 3rd and 4th gear and ...

2003年10月6日 · S4 / RS4 (B5 Platform) Discussion - DTC: 18047 - Accelerator Pedal Pos. Sensor 1/2 (G79/G185): Implausible Signal? - Recently, when I accelerate full throttle with my car, the ABS, EPC, Trac Control, and occasionally the Check Engine lights come on …

2012年3月31日 · There are 2 sensors in the accelerator pedal, both should increase in the same direction as the accelerator is pressed but they have different scales. This means one counts from 0 to 100, while the other one counts from 0 to 50. Accelerator Position Sensor faults can be caused by issues with the Oxygen Sensor (s) and it's wiring.

2016年10月26日 · Ross-Tech suggests the accelerator pedal sensors rarely take a ****, however, the O2 sensors and their wiring may be a culprit. This car had JHM downpipes installed a couple years ago and I assume the installer reattached the O2 sensors correctly. I also sent the ECU and TCU to JHM a couple years ago for upgraded tunes.

2010年6月30日 · Yesterday whilst doing about 65 on the motorway, the EPC, ESP and ABS warning lights came on the dash and it went into what i believe is refered to as 'limp mode'. I couldnt increase my speed and acceleration was non existent.

2016年12月31日 · I'm getting a p2138 "Accelerator Position Sensor 1/2 (G79) + (G185), Implausible Signal". There's an ongoing problem with the ABS/ESP warning lights but I don't think it's related. I've been driving the car for a number of months with the ABS/ESP coming on after 5 minutes of driving.

Today the car went into limp mode with warning triangle light and flashing coil light. Turn it off and restart and the car behaved fine again for a short while and then did it again. I cleared the engine and ABS fault codes in the attached scan and they reappeared so …

There is no common short, but it looks like it is in the manifold area according to the faults. That is what they seem to have in common. The faults may also be a result of the blown fuses. I am assuming that the fuse are blowing all the time, every time. Is that right? The transmission is not recieving information that it needs to make decisions.
