Base Ignition Timing Inspection: Sedona

Ensure engine is at normal operating temperature. Turn off all electrical loads. Set transaxle in Park or Neutral and steering wheel on straight forward position. Ground ignition timing adjustment terminal of underhood Data Link Connector (DLC). See Figure. Start engine and allow it to idle. Check base ignition timing. Timing mark on crankshaft pulley and mark on timing belt cover should be aligned to specification. See BASE IGNITION TIMING  table. If timing is not within specification, check for faulty sensor or incorrect camshaft timing. Check power and grounds. If camshaft timing, sensors, power and grounds are okay, replace Engine Control Module (ECM).
