    I'm getting a Do Not Shift light and CEL. I pull the code and it's a SID0385 Accelerator Pedal code. I had a mobile HT mechanic come out and he said it was the sensor on the pedal. I went and got one and replaced the old. It worked great for a day. Lights were gone and code was clear. Started it back up yesterday after an oil change, lights and code are back. I'm lost here. Any help is greatly appreciated!!

    I’m pretty new at this. But it’s been said to me that the pedal could be getting worn out. And tweaking the app.for sure you had a look at your wiring?

    It's the short harness. I unplugged it and plugged back in.. lights/code gone. I pulled it back off and added terminal grease to the pins. Looking for a new harness but have not been successful. It is a flat 6 pin at sensor 134143 and square 6 pin at the harness. Pic is the correct harness but wrong sensor..
