On the harness that connects to the 02 sensor, it is a 4 wire plug. I have a smaller disconected 5th wire. What is that and where does it go? I just replaced my o2 sensor and i am still getting o2 sensor and o2 wiring codes. Please help,
I also have 00515 Hall sensor code
I have reset the placement of 2 different distributors and i still have the code. I know that the timing is right, and what is the chances that both sensors went bad? It was running fine until one day this code decided to come up. Any help?
