Checking wiring
Check the engine control module (ECM) and canister purge (CP) valve connectors. Check for contact resistance and oxidation.
Check that the resistance in the canister purge (CP) valve between terminals #1 and #2 is approximately 21 ohms at +20°C.
Check the signal cable between engine control module (ECM) terminal #4 and canister purge (CP) valve terminal #1. Check for an intermittent open-circuit. Remedy if necessary.
Check the power supply cable between the canister purge (CP) valve terminal #2 and system relay (2/14) terminal #5. Check for an intermittent open-circuit.
