Diagnostic Test
- CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-I
- Turn ignition switch OFF.
- Disconnect exhaust valve timing control solenoid valve harness connector.
- Check resistance between exhaust valve timing control solenoid valve terminals as per the following.
Exhaust valve timing control solenoid valve Resistance + - Terminal 1 2 7.0 - 7.7 Ω [at 20°C (68°F)] 1 Ground ∞Ω
(Continuity should not exist)2
Is the inspection result normal?
YES
GO TO STEP 2 .
NO
Replace exhaust valve timing control solenoid valve. Refer to EXPLODED VIEW .
- CHECK EXHAUST VALVE TIMING CONTROL SOLENOID VALVE-II
- Remove exhaust valve timing control solenoid valve. Refer to EXPLODED VIEW .
- Provide 12 V DC between exhaust valve timing control solenoid valve terminals 1 and 2, and then interrupt it. Check that the plunger moves as shown in the figure.
CAUTION:
Do not apply 12 V DC continuously for 5 seconds or more. Doing so may result in damage to the coil in exhaust valve timing control solenoid valve.
NOTE:Always replace O-ring when exhaust valve timing control solenoid valve is removed.
Is the inspection result normal?
YES
