Ignition Timing: Adjustments
PREPARATION1. Warm up the engine to normal operating temperature.
2. Turn all electrical loads OFF.
- Headlight switch
- Fan switch
- Rear window defroster switch
3. Connect a tachometer to the data link connector terminal IG- as shown.
Ignition Timing
1. Perform "Preparation". (Refer to above.)
2. Verify that the idle speed is within the specification; if not, adjust it.
Idle Speed:
(Neutral): 800-900 (850 ± 50) rpm (MT)
(P range): 750-850 (800 ± 50) rpm (AT)
3. Connect a jumper wire between the TEN terminal and the GND terminal of the data link connector.
4. Verify that the idle speed is within the specification.
Idle speed: 650-975 rpm (Terminal TEN grounded)
5. 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])
6. If the marks are not aligned, remove the ignition coil bracket and push the ignition coil aside for easy access and then loosen the camshaft position sensor lock bolts, and turn the camshaft position sensor to make the adjustment.
7. Tighten the distributor lock bolts to the specified torque.
Tightening torque: 19-25 N.m (14-18 ft.lb)
8. Disconnect the jumper wire from the data link connector.
9. Increase the engine speed and verify that the ignition timing advances.
