Electronic Ignition Timing Control

Ignition timing is controlled by PCM and is not adjustable. If ignition timing is not within specification, check for an engine mechanical failure. To check ignition timing, see ELECTRONIC IGNITION TIMING INSPECTION. If ignition signal is not present at PCM, Diagnostic Trouble Codes (DTCs) P1300 and P1310 can set in PCM memory. For testing procedures, see TESTS W/CODES article.
