Is there an easier method for testing the purge solenoid on a 1994 Dakota. My scan tool indicates DTC 31-purge valve solenoid. I have tested it for voltage to the dark blue power line. I bench tested the relay and it does activate. I can clear the code and it does not reappear until the engine gets warm. I have continuity from connector 52 on the computer plug and 0 ohm reading the pink wire but with black tracer at the relay. Why does the code keep reappearing? I need help with a test.
