Theory of Operation

The EGR Valve position is monitored by the Powertrain Control Module (PCM). The purpose of this monitor is compare the EGR Valve actual position to position commanded by the PCM. If these values differ by a significant value for an extended period of time in two consecutive drive cycles, the PCM will turn on the MIL Light, and EGR flow will be disabled.

- When Monitored:
Continuously with the ignition on, and no other EGR Valve DTCs present.

- Set Condition:
The PCM detects a significant difference between the EGR actual position and commanded position for and extended period of time.





Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Pre-Diagnostic Troubleshooting Procedure.

1. CHECK FOR ACTIVE DTC

NOTE: If other EGR related DTCs are present and active, repair those DTCs before proceeding.

1. Start the engine and test drive the vehicle.
2. With the scan tool, View all active DTCs.

Is the DTC Active?

Yes

- Go To 2

No

- Perform the INTERMITTENT CONDITION - 6.7L diagnostic procedure. Intermittent Condition Test

2. CHECK THE EGR VALVE
1. With the scan tool, Erase DTCs.
2. Turn the ignition off.
3. Remove and clean the EGR valve with Mopar EGR Valve cleaner. Procedures.
4. Start the engine and test drive the vehicle.
5. With the scan tool, View DTCs.

Did the DTCs return?

Yes

- Replace the EGR Valve. Exhaust Gas Recirculation (EGR) Valve - Removal.
