Service
-
Carefully inspect black EGR vacuum line where it passes over EGR Valve.
Note:
The black vacuum line may-be routed too close to the mechanical EGR Valve. If so, the vacuum line could eventually rub through causing a vacuum
leak which turns on the MIL and stores an EGR malfunction.
-
Replace black EGR vacuum line if necessary. Ensure that vacuum line is routed away from EGR Valve.
