I got this as my error code from the ECU. Anyone know what this is, how easy it is to replace? Price? Thanks. I'd do a search but it wont let me still.

 

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

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.

The EVAP canister and this valve are located under the car, near the rear left tire. You might check to make sure all the electrical connectors in that area are secure.

There's no telling how expensive the repair will be, because no definite diagnosis has been made. Maybe you just have to re-plug a loose connector. Since the EVAP system is part of the emissions control system you might have warranty coverage.


Anyone have this replaced and know what it costs roughly?

 

I had my VCV replaced at a Nissan dealer about 2 years ago - seems like it was $125-150, parts and labor.

Not sure how much of that was for the part, or how difficult it would be to change yourself.

 

I've had an EVAP code on my wifes car for about 20,000 miles now. Other than being annoying, the car runs fine.
