IGNITION TIMING INSPECTION
1. Perform "Engine Tune-up Preparation". Refer to Maintenance; Tune-up and Engine Performance Checks; Service and Repair.
2. Verify that the idle speed is within the specification.
Specification: 750 - 850 (800 ± 50) rpm
3. If not as specified, adjust the idle speed.
4. Connect the SST (System Selector) to the data link connector.
5. Set switch A to position 1.
6. Set the test switch to SELF TEST.
7. Connect a timing light to the high-tension lead of the No.1 cylinder.
8. Verify that the timing mark (white) on the crankshaft pulley and the T mark on the timing belt cover are aligned.
Ignition timing: BTDC 9° - 11° (10° ± 1°) (TIMING MARK [YELLOW])
9. Disconnect the SST (System Selector).
10. Verify that the timing mark (yellow) is within the specification.
Specification BTDC 6 - 18°
11. If not as specified, inspect the following.
^ Camshaft position sensor
^ Crankshaft position sensor
^ Throttle position sensor
^ Engine coolant temperature sensor
^ Neutral switch (MT)
^ Clutch switch (MT)
^ Transmission range switch (AT)
12. If the devices are normal, replace the PCM.
