I have found something but I don't know if it caused anything? The thick ground wire (Black) from the starter is run right next to the exhaust pipe, and some of the rubber is melted off of the side of the wire, and the raw copper is touching the exhaust pipe.
would this effect anything? It is only a ground wire, but it is close enough to the O2 sensor, maybe it is what caused the code 41 i'm getting?

 

ya think??????

 

The bigger problem is that the rubber is melted, allowing water to get into the wire and corrode it. I use zip-ties to route the wires out of the way of the exhaust.

 

clean it up and put some shrink on it and reroute away from 02Sensor definitely
..good luck

 

Yes I already did that. I guess I was just asking if the ground from the starter with contact to the exhaust pipe about 2 feet from the o2 sensor will damage the sensor or cause the code 41?

I doubt it, a ground is a ground regardless of where it connects to the body and or motor. Regardless of it grounding out there at any given time intermittently or all the time wouldn't really make much difference. The motor is grounded as long as that cable was intact and solidly connected at each end, it was intact other then the melted casing right?
The O2 sensor are generally grounded up on top of the motor to the intake, so the motor is grounded via that cable, the O2 sensor is grounded via the engine block through the same cable.

From what I've seen no grounding supplied for 02 sensors throws a "secondary fuel system fault" (words to that effect) type code.

Having said that the only way to know for sure is to clear the codes and see if it comes back.

You are sure that is a ground cable to the starter right?
