Evap Canister Purge Solenoid Diagnosis
I have a 1997 Ram 1500, 5.2L Auto 4x2. My MIL came on and after cycling the ignition switch on-off-on-off-on, I get code 31, which indicates a problem with the Evap Canister Purge Solenoid Circuit. How can I confirm that it's the solenoid that's bad, as opposed to an electrical problem? Do I test the voltage to the solenoid with the engine running and warmed up? Is it 12v that I'm looking for? Or can I just do a continuity test on the solenoid itself (with electrical disconnected)? Thanks for any help!
