I am chasing a ECT sensor issue with a constant code 21. Here is what I have found:
1. Straight short between the two pins for the sensor (so I believe this is bad)
2. Wiring has been traced and verified good connectivity
3. There are TWO Yellow/green line wires going to 1 pin , the other is green/black line (sensor ground)
I plan on replacing the sensor as it seems to not measure out correctly. BUT, are there supposed to be two Yellow/green line wires to the same pin? I can only find 1 on the harness connection at the ECU, so I am wondering if something is amiss there?
