EGR VALVE INSPECTION [AJ] (VIN: JMZ LW19J7*# 300001-, JM0 LW10J300 300001-301405, JM6 LW10J300 300001-, JM8 LW28J**# 300001-301513)

Resistance Inspection

Note

• Perform the following test only when directed.

1. Disconnect the negative battery cable.

2. Inspect resistance of the EGR valve coils.

• If not as specified, replace the EGR 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 valve terminal E (harness-side) and PCM terminal 12

- EGR valve terminal A (harness-side) and PCM terminal 72

- EGR valve terminal B (harness-side) and PCM terminal 46

- EGR valve terminal F (harness-side) and PCM terminal 56

- EGR valve terminal C or D (harness-side) and main relay terminal D (harness-side)

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

- EGR valve terminal E (harness-side) and GND

- EGR valve terminal A (harness-side) and GND

- EGR valve terminal B (harness-side) and GND

- EGR valve terminal F (harness-side) and GND

- EGR valve terminal E (harness-side) and power supply

- EGR valve terminal A (harness-side) and power supply

- EGR valve terminal B (harness-side) and power supply

- EGR valve terminal F (harness-side) and power supply

- EGR valve terminal C or D (harness-side) and power supply

3. Remove the EGR valve, and inspect for any damage or clogging.

• If there is no damage or no clogging, replace the EGR valve. (See INTAKE-AIR SYSTEM REMOVAL/INSTALLATION [AJ].)
