Set Conditions
- Set Condition:
The PCM monitors the EGR position rationality by subtracting the actual position of the EGR valve from the desired position. If the value exceeds a calibrated value for a calibrated time, the test fails. If the PCM detects that the EGR position zero reference voltage is not within a valid range, the test fails. After two failed trips, a DTC is set and the MIL is illuminated.
