Summary
Should a customer express concern about one of the following:
* hesitations,
* poor or no start,
* deteriorated fuel economy,
and upon investigation diagnostic trouble codes (DTC) P1412, P0490 and P1335 are stored in the powertrain control module (PCM), the probable cause is a sticky exhaust gas recirculation (EGR) valve.
To rectify this concern, a new EGR valve with a stronger EGR valve motor and revised PCM calibration should be installed.
NOTE: Use CD-42 or a later version.
