🔧 Mass Air Flow Sensor - Replacement

🔨 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 your Stinger.
• Use the 8mm socket and ratchet to loosen the intake clamp if it blocks access.
• Use a Phillips screwdriver if the sensor is retained by screws on the housing.

Step 2: Disconnect the MAF sensor

• Press the connector lock tab and unplug the electrical connector from the sensor.
• Use your fingers only unless the connector is tight. If needed, use a trim panel tool gently.
• Do not pull on the wires.

Step 3: Remove the old sensor

• Use the Phillips screwdriver to remove the sensor screws.
• Lift the MAF sensor straight out of the housing.
• Check the sealing surface and the intake tube for dirt or damage.

Step 4: Install the new sensor

• Position the new MAF sensor in the same direction as the old one.
• Install the screws by hand first, then tighten with the Phillips screwdriver.
• Torque to 2-3 Nm (18-27 in-lbs) if a torque spec is needed for the screws.

Step 5: Reconnect and reassemble

• Plug the electrical connector back in until it clicks.
• Reinstall any intake tube clamp using the 8mm socket and ratchet.
• Make sure all clamps are snug and the air box is sealed.
