TEST
1 Turn the ignition on.
With the DRBIII , read the EGR Position Sensor voltage.
Is the voltage below 0.2 of a volt?
Yes → Go To 2
→ Go To 10
No
2 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
Turn the ignition on.
Measure the voltage of the 5 Volt Supply circuit in the EGR Solenoid harness
connector.
Is the voltage between 4.5 to 5.2 volts?
Yes → Go To 3
→ Go To 7
No
3 Turn the ignition off.
Disconnect the EGR Solenoid harness connector.
With the DRBIII , monitor the EGR Position Sensor voltage.
Turn the ignition on.
Is the voltage above 4.5 volts?
Yes → Replace the EGR Solenoid Assembly.
→ Go To 4
No
