Electronic Ignition Timing Advance

Ignition timing is controlled by Engine Control Module (ECM). If ignition signal is not present at ECM, DTC 41 will set in ECM memory. For testing procedures, see TESTS W/CODES - 1.0L 3-CYL article. If a fault occurs in camshaft position sensor circuit or camshaft position sensor fails, DTC 42 will set in ECM memory. For testing procedures, see TESTS W/CODES - 1.0L 3-CYL article. For adjusting procedures, see IGNITION TIMING in the ADJUSTMENTS - 1.0L 3-CYL article.
