PR25DD engine

1. Turn ignition switch OFF.
2. Disconnect exhaust valve timing intermediate lock control solenoid valve harness connector.
3. Check resistance between exhaust valve timing intermediate lock control solenoid valve terminals as follows.

   Terminals	Resistance
   1 and 2	7.0 - 7.5 Ohm [at 20 deg. C (68 deg. F)]
   1 or 2 and ground	INF.Ohm (Continuity should not exist)

Is the inspection result normal?

YES

GO TO 2.

NO

Replace exhaust valve timing intermediate lock control solenoid valve. Refer to CAMSHAFT : Exploded View .

1. Remove exhaust valve timing intermediate lock control solenoid valve. Refer to CAMSHAFT : Exploded View .
2. Provide 12 V DC between exhaust valve timing intermediate lock control solenoid valve terminals 1 and 2, and then interrupt it. Make sure 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 intermediate lock control solenoid valve.
   NOTE: Always replace O-ring when exhaust valve timing intermediate lock control solenoid valve is removed.
