Engine warning light will not go off after starting engine-replaced cap light still stays on
What is your question?
What should I check to turn off "Check Engine" warning light after engine is started. Checked the problem with my OBD 2 Code Reader - It reported a code error P2402 which seems to be a problem with Evaporative Emission System Detection Pump Control Circuit High which means faulty vacuum pump or open vacuum module harness or poor electrical connection. also faulty Engine Control Module (ECM). Where is the vacuum pump module located in the car.
What makes this problem better or worse?
no change - on all the time-just took trip to NJ approx 350 miles with no change
