Tools you will need
- Flat blade screwdriver
- 10 mm socket and ratchet
- Phillips screwdriver
Parts and supplies
- Mass airflow sensor or sensor housing as required
Steps
Open the airbox
Switch off the ignition and unplug the airflow-sensor connector. Loosen the intake clamp, release the airbox clips, and move the vacuum hoses aside without stretching them.
Remove the old sensor
Lift the airbox cover away and remove the sensor fasteners. If replacing the sensor element only, separate it from its housing and retain the original housing if undamaged.
Install the replacement
Fit the new sensor in the same orientation and secure it to the housing. Align the cover tabs with the airbox slots and close all retaining clips.
Reconnect the intake
Reconnect both vacuum hoses, seat the intake tube fully, and tighten its clamp. Plug the sensor harness in until its lock engages.
Check operation
Inspect the intake joints and hose routing before starting the engine. Confirm normal idle and check for warning lights or air leaks.
Check your vehicle’s repair manual for exact specifications and fit.
