Ok, so cruisin' on the highway this morning & I notice my SES light come on. I just checked it out, its 0705 and 0903. According to the FAQ:

0903
Diagnostic Trouble Code 0903 indicates a problem with the Evaporative Emission (EVAP) Canister Vent Control Valve or its associated electric circuit.

What I want to know is for those of you who had this DTC, what was the real cause and/or fix? The FAQ basically states to check all electrical connections in the area, and while I didn't have the rear of the car jacked up, I didn't see any loose connectors or hoses in the area. The car drives fine, and I reset the SES so I'll see if it comes on again tonight or tomorrow, but I just wanted to see what the problem was for others who've had it.

Thanks!

 

This part is used by the Engine Control Module to perform the fuel system leak test. Since it is used only for self-diagnosis your engine will run perfectly well despite the dashboard Malfunction Indicator Lamp.

 

Yeah, I read that part too... Other than regurgitating the FAQ, does anyone know if it's because a part needs replacing (the car only has 51K) or is it something like a dirty connector?

I just don't want it to come back since in NJ, I'd fail inspection just 'cause the SES is on.

 

Hmm. I would dissconnect the connecter and plug it back it. Make sure the wires arent't corroded.
