🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air intake area

• Open the hood and locate the air filter box and intake tube on the top of the engine bay.
• Use the Phillips screwdriver or 8mm socket to loosen the intake hose clamp if it blocks access to the sensor.
• Keep the intake opening clean.

Step 2: Disconnect the MAF sensor connector

• Press the connector lock tab and unplug the wiring connector from the MAF sensor.
• If the tab is tight, use a small pick tool gently to help release the lock.
• Do not pull on the wires.

Step 3: Remove the old sensor

• Use the Phillips screwdriver or 8mm socket to remove the sensor retaining screws.
• Lift the sensor straight out of the housing.
• Inspect the seal or O-ring and remove it if it comes out with the sensor.

Step 4: Install the new sensor

• Place the new MAF sensor seal or O-ring in position if needed.
• Install the new sensor into the housing in the same direction as the old one.
• Use the Phillips screwdriver or 8mm socket to tighten the retaining screws.
• Torque to 3-4 Nm (27-35 in-lbs).
• Snug is enough here.

Step 5: Reconnect the intake and wiring

• Reconnect the wiring connector until it clicks.
• Reinstall and tighten the intake hose clamp with the Phillips screwdriver or 8mm socket.
• Make sure the air intake tube is fully seated and there are no gaps.

Step 6: Start and verify

• Start the engine and let it idle.
• Check for a smooth idle and make sure the check engine light is off.
• If the light stays on, clear the code with a scan tool and recheck the connector and intake seals.

✅ After Repair
