Hey guys, I am receiving this error code and alternatively will receive a P0458 (Low Voltage) code when I unplug the valve connector. Here is what I have done to pinpoint the issue:
- Valve was replaced and confirmed to function by bench testing
- 12V is being sent to terminal 1 of the wiring harness
- Valve will operate if I manually ground the valve to the chassis
- Using the cars "test mode" I can see terminal 2 cycling between ground and open circuit, the valve however does not function
- There is approx. 35 ohms of resistance when measuring between the two harness terminals with it unplugged from the valve.
- When I unplug the main wiring harness the resistance of the two terminals jumps to open circuit.
- I removed approx 5 inches of protective cover from the wires to inspect for damages/shorts and none were found.
I'm really hoping this isn't a bad ECU issue but am having a feeling it might be... any thoughts of where to go from here?
What makes this problem better or worse?
