Please feel free to ask follow up questions, it is part of the process.


If you were not getting the code before the new harness, there has to be an issue in the new harness or a connector, or there is a problem with the injector caused by the previous damage.

I would try swapping the suspect injector with another and see if the code moves with it.

I had the code initially, and it hasn't gone away with the new harness. I also swapped out the injector in the process. Still the same code.



If you are sure there is not a short or open in the circuit and the injector is good, then it is the PCM that is bad. It is known to happen though it is the least common cause for this code.

I ended up replacing the PCM. That fixed the problem.


Glad it is fixed. To bad it was the PCM.
