## 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".

Terminals | Resistance (ohm)
--- | ---
C-E C-A D-B D-F | 8-9

## Circuit Open/Short Inspection

1. Disconnect the PCM connector. (See PCM REMOVAL/INSTALLATION [L3 Turbo].)

2. Inspect the following wiring harnesses for open or short circuit (continuity check).

Open circuit

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

  - EGR valve terminal E and PCM terminal 4D
  - EGR valve terminal A and PCM terminal 4G
  - EGR valve terminal B and PCM terminal 4J
  - EGR valve terminal F and PCM terminal 4M
  - EGR valve terminal C or D and main relay terminal C

Short circuit

  • If there is continuity, there is a short circuit. Repair or replace the wiring harness.

  - EGR valve terminal E and Ground
  - EGR valve terminal A and Ground
  - EGR valve terminal B and Ground
  - EGR valve terminal F and Ground
  - EGR valve terminal C or D and power supply

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

  • If there is no damage or clogging, replace the EGR valve.
