Steps
Disconnect the sensor
Turn the ignition off and locate the airflow sensor in the intake tract. Release the harness lock and unplug the connector without pulling on the wires.
Remove the old sensor
Remove the sensor retaining screws and lift the sensor and its seal from the housing. Keep dirt out of the intake opening and inspect the seal for damage.
Install the replacement sensor
Seat the new sensor with its seal correctly positioned and align it in the original direction. Install the screws evenly and reconnect the harness until its lock engages.
Verify the repair
Check that the sensor is secure and the intake opening remains sealed. Start the engine and confirm normal idle and warning-light behavior.
