Ignition Timing: Testing and Inspection
Ignition Timing Inspection
1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or Neutral) until the radiator fan comes on, then let it idle.
2. Check the idle speed.
3. Connect the Honda PGM Tester to the Data Link Connector (DLC), and follow the tester's prompts in the "SCS" menu (see the Honda PGM Tester Operator's Manual).
4. Connect the timing light to the service loop.
5. Point the light toward the pointers (A) on the timing belt cover. Check the ignition timing under no load conditions: headlights, blower fan, rear window defogger, and air conditioner are not operating.
6. If the ignition timing differs from the specification, replace the ECM/PCM.
7. Disconnect the Honda PGM Tester and the timing light.
