These are the things I've been able to test:
- The PWM/VSV/purge solenoid in the engine bay with a 9v battery. Healthy click - all good
- The volts going to above valve. 12V - all good.
- I've managed to wiggle some probes and 9v battery around in the power socket (there are 8 male pins) for the charcoal canister, near the muffler, and the pump runs.
- I measured the volts going to the charcoal canister and there is 5v, 12v, and 5-10 variable volts on three pins, 0v on the rest. I think there are nine female sockets in the plug.
- All hoses and lines look healthy.
- If I clear the code, it comes back instantly.
- The diagram under the hood says there is another valve in the engine bay (as well as the purge valve) but I can't find that either.
So, would anybody be able to help with:
- The location of the vent valve
- The location of the mystery extra valve in the engine bay
- The voltages I should be expecting on the plug going to the charcoal canister?
Cheers in advance!
