Air Flow Meter/Sensor: Service and Repair

REMOVAL AND INSTALLATION






1. Disconnect the battery ground cable.

NOTE: When battery voltage is removed from the Powertrain Control Module (PCM), all learned values will be cleared and reset to predetermined values. When battery voltage is restored to the PCM, the vehicle may exhibit certain driveability concerns. It will be necessary to drive the vehicle to allow the PCM to relearn values for optimum driveablilty and performance.
