Note
-
• Perform the following test only when directed.
1. Remove the battery cover. (See BATTERY REMOVAL/INSTALLATION[L3 Turbo].)
2. Disconnect the negative battery cable.
3. Disconnect the EGR valve connector.
4. Measure the resistance between the EGR valve terminals.
-
• If within the specification, perform out the “Circuit Open/Short Inspection”.

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 A and PCM terminal 2AM
― EGR valve terminal B and PCM terminal 2AR
― EGR valve terminal C or D and main relay terminal A
― EGR valve terminal E and PCM terminal 2AQ
― EGR valve terminal F and PCM terminal 2AN
-
Short circuit
-
• If there is continuity, there is a short circuit. Repair or replace the wiring harness.
-
― EGR valve terminal A and power supply
― EGR valve terminal A and body ground
― EGR valve terminal B and power supply
― EGR valve terminal B and body ground
― EGR valve terminal C or D and body ground
― EGR valve terminal E and power supply
― EGR valve terminal E and body ground
― EGR valve terminal F and power supply
― EGR valve terminal F and body ground
3. Remove the EGR valve, and inspect for any damage or clogging.
