TEST
6 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Turn the ignition on.
Measure the voltage of the EGR Sensor Signal circuit at the EGR Solenoid harness
connector.
Is the voltage above 4.30 volts?
Yes → Go To 7
→ Go To 8
No
7 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the Sensor Ground circuit from the EGR Solenoid harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Replace the EGR Assembly.
→ Repair the open in the Sensor ground circuit.
No
8 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the EGR Sensor Signal circuit from the EGR Solenoid
harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 5.0 ohms?
Yes → Go To 9
→ Repair the open in the EGR Sensor Signal circuit.
No
9 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Disconnect the PCM harness connector.
Measure the resistance between ground and the EGR Sensor Signal circuit in the
EGR Solenoid harness connector.
Is the resistance below 100 ohms?
Yes → Repair the short to ground in the EGR Sensor Signal circuit.
→ Go To 10
No
