EGR BOOST SENSOR SOLENOID VALVE INSPECTION [AJ] (VIN: JM0 LW10J300 301406-, JMZ LW69J7*# 307683-, JM8 LW28J**# 301514-, JM8 LW28A**# 301514- (Assumed))

Airflow Inspection

Note

• Perform the following test only when directed.

1. Disconnect the negative battery cable.

2. Remove the EGR boost sensor solenoid valve.

3. Inspect airflow between each port under the following conditions.

• If not as specified, replace the EGR boost sensor solenoid valve.

• If as specified, carry out the "Circuit Open/Short Inspection".

Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [AJ].)

2. Inspect the following wiring harness for open or short (Continuity check).

• If there is no continuity, the circuit is open. Repair or replace the harness.

- EGR boost sensor solenoid valve terminal B and PCM terminal 93

- EGR boost sensor solenoid valve terminal A and main relay terminal D

• If there is continuity, the circuit is shorted. Repair or replace the harness.

- EGR boost sensor solenoid valve terminal B and body GND

- EGR boost sensor solenoid valve terminal B and power supply
