Just got these codes this morning...

P0443: EVAP Purge solenoid Valve 1 Control Circuit

P0645: Air Conditioning Clutch Relay Control Circuit

I find it odd that both of these would go out at the same time...even so, has anyone had any success in fixing these? I can't do much about it over the next 3 days, have to wait until my break days (Mon-Tue). Just wanted to see if anyone could lay some wisdom on me, before I check my FSM Smile

Update: All fuses/relays and the A/C all appear to be operating normally.

Anyone have any clues?

Hmmm sounds like something there got hot, but not hot enough to blow a fuse. Thats odd.

Is the AC working okay? Notice anything suspicous with it?

Try disconecting the battery to reset the epu? I know that dosent work for everything but ya never know.

Heh, get this...I fill'er up this morning, make sure to tighten the cap down (testing a theory) and YEP, the SES light turns off...WEIRD. The gas cap code wasn't even emitted by the PCM!!! I know that one well, its P0442.

I'm going to keep an eye on it though...it's all a tad fishy to me...
