2. 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.

DTC DETECTION LOGIC

NOTE:

• If DTC P0087 is displayed with DTC P0090 and/or P1197, first perform the trouble diagnosis for DTC

P0090 and/or P1197. Refer to 

EC-826, "DTC Logic"

 and/or

EC-1071, "DTC Logic"

.

• DTC P0087 may be displayed when running out of gas or air accumulation.

DTC CONFIRMATION PROCEDURE

1.

CHECK FUEL LEAKAGE

1. Turn ignition switch ON.

2. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.

3. Start the engine.

4. Visually check the piping between low pressure fuel pump and fuel injectors for fuel leakage.
Is inspection result normal?

YES

>> GO TO 2.

NO

>> Repair or replace error-detected parts.

2.

PRECONDITIONING

If DTC CONFIRMATION PROCEDURE has been previously conducted, always perform the following proce-

dure before conducting the next test.

1. Turn ignition switch OFF and wait at least 10 seconds.

2. Turn ignition switch ON.

3. Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:

• Before performing the following procedure, confirm that battery voltage is 11 V or more at idle.

• Before performing the following procedure, check that the fuel tank is 1/8 full of fuel.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE-1

WITH CONSULT

1. Turn ignition switch ON.

2. Select “COOLAN TEMP/S” in “DATA MONITOR” mode of “ENGNE” using CONSULT.
