🔧 MAF Sensor - Replacement

The mass air flow sensor on your XC60 measures the air entering the engine so the engine computer can set fuel delivery correctly. If it fails, you may see rough idle, poor acceleration, or a check engine light. This job is usually quick and straightforward because the sensor sits in the intake tract near the air filter box.

Difficulty Level: Beginner | Estimated Time: 0.5-1 hour

⚠️ Safety & Precautions

• Turn the ignition off and remove the key/fob before unplugging anything.
• Let the engine cool if it has been running; intake parts can be hot.
• Do not touch the sensing element inside the MAF sensor. It is very fragile.
• Use only the correct cleaner if you are inspecting the intake. Do not use brake cleaner or compressed air on the sensor.
• Battery disconnect is not usually required for this repair, but keep the ignition off the whole time.
