Intermittent Diagnostic Trouble Codes DTCS

If DTC is intermittent and malfunction is not present, problem may not be located while performing diagnostic tests. In this case, stored DTC can only suggest an area to inspect.

If intermittent DTCs are set, check for loose or corroded connections, damaged components, and damaged wiring. If no obvious problems are found, erase stored DTCs. With ignition on, wiggle wiring harness and connectors. Recheck for DTCs periodically as you work through system. This procedure may uncover a difficult to locate problem.
