EGR Control Solenoid: Description and Operation
Diagnostic Check Operation
The solenoid disables the EGR system periodically, to allow the PCM to perform a diagnostic check.
-
During a diagnostic check, (activated only during select engine/driving conditions), the PCM tests the entire EGR system for failures.
-
If the PCM detects an EGR system failure, the Malfunction Indicator Lamp (MIL), (previously called the Check Engine Lamp), in the
instrument panel will be illuminated, indicating that immediate service is required.
