Thread: P0641 Code

I found the problem. The ECT (engine coolant temperature) sensor is broken. This is why there is a loss of engine power. If this sensor gets damaged it affects the fuel control system, and the 5 volt bus to the ECM.
I found it when I was inspecting sensors around the engine, and I saw the ECT sensor has black tape wrapped around it. The sensor was very loose when I touched it. I removed the tape and found the sensor body for the wire connection is broken.
I now remember how this got like that. The idiot body shop did this when the front grill and radiator was replaced. They never bothered to tell us that they broke it and tried to do a quick fix by taping it. Morons.
