Truck runs fine but can't erase the code. Unplug the VP44 and still, the code remains. Now if he removed the fuel pump relay in the PDC it would erase the code but return instantly if the relay was plugged back in. This owner also admitted to having a BD noise filter as well. I told him to test the alternator for excessive AC noise. Back to the VP44 code, he mentions he had a second pump. So I had him just plug it in without installing the pump and the code erased and stayed out. So again another AC noise story that ate a VP44 because the owner was battling the torque converter lock up issue and ate the VP44 with excessive AC noise.
The owner called me today and had a p0232 code.
