⚠️ Safety & Precautions

• Turn the engine off and let it cool before working near the air intake.
• Do not touch the sensor element inside the MAF sensor; it is very delicate.
• Disconnect the negative battery cable only if you want to clear adaptive memory the hard way; it is not required for this job.
• Keep dirt, leaves, and tools out of the open air intake tube.

🔨 Step-by-Step Instructions

Follow these steps in order:

Step 1: Open the air intake area

• Open the hood and locate the air intake tube between the air filter box and the throttle body.
• Use an 8mm socket or a small flat-blade screwdriver to loosen any clamps if needed for access.
• Remove the engine cover only if it blocks access, using a trim tool or by lifting it straight up.

Step 2: Unplug the MAF sensor

• Find the MAF sensor in the air intake tube or air filter housing.
• Press the connector lock tab and unplug it by hand.
• Do not pull on the wires.

Step 3: Remove the sensor

• Use an 8mm socket and ratchet to remove the MAF sensor screws.
• Lift the sensor straight out of the housing.
• If it sticks, gently wiggle it free without forcing it.

Step 4: Install the new sensor

• Compare the new sensor to the old one to make sure it matches.
• Install the new sensor in the same direction as the old one.
• Start the screws by hand first, then tighten with the 8mm socket.
• Tighten snugly to 3-5 Nm (27-44 in-lbs).

Step 5: Reconnect everything

• Plug the electrical connector back into the MAF sensor until it clicks.
• Reinstall any intake tube clamps or covers you removed using the 8mm socket or small flat-blade screwdriver.
• Make sure all hoses and clamps are seated fully.
