This is on a 1997 Max...anyone receive this combo and have a fix? The codes are somewhat ambiguous.

Thanks!

 

0903 - Evap Canister Vent Control Valve
0705 - Evap Control System (small leak)
If both 0903 and 0705 are displayed, troubleshoot 0903, the valve, first.
The valve itself is on the canister where the vent hose enters. Possible code causes include, Harness or Connectors, the Canister Vent itself, the EVAP Control System Pressure Sensor, A blocked Tube to the Valve, or Water Separator. The valve is easy to check. Unhook it and you should be able to blow through it. Apply 12V to the two terminals and you should not be able to blow through it. Try this first.

 

I ended up replacing the canister and valve and it's all better now.
