Ignition Timing: Testing and Inspection

Ignition Timing Inspection
SRS components are located in this area. Review the SRS component locations, precautions, and procedures in the SRS section before performing repairs or service.
1. Start the engine. Hold the engine at 3,000 rpm with no load (shift lever in [N] or [P] position) until the radiator fan comes on, then let it idle.
2. Pull out the service check connector located under the glove box. Connect the GRN/BLU and ORN wire terminals with the special tool.






3. Check the idle speed.
4. Connect a timing light to the service loop; while the engine idles, point the light toward the pointer on the timing belt cover.






5. Inspect ignition timing at idle speed.

Ignition Timing:
15° ± 2° BTDC (RED) at 640 ± 50 rpm with shift lever in [N] or [P] position and electrical systems turned off.






6. If the ignition timing is incorrect, replace the PCM (there is no way to adjust ignition timing).
7. Disconnect the special tool from the service check connector.
