If solenoid valve operates, go to next test. Remove EGR and canister control solenoid valve. Apply battery voltage and ground to terminals No. 1 and 2. See Figure. With battery voltage applied, air should pass between ports "A" and "B". Air should not pass between ports "A" and "C". With no voltage applied, air should pass between ports "A" and "C". Air should not pass between ports "A" and "B". Replace EGR and canister control solenoid valve if not as specified. If solenoid valve is okay, go to next test.
