MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR
REMOVAL
1. Ignition Off.
2. Remove air induction tubing from throttle body to air cleaner.
3. Disconnect MAP sensor harness connector.
NOTE: MAP sensor is held in by a retaining clip, there is no hold down bolt or screw. Be careful when removing MAP sensor from clip. The clip is brittle and may break with excessive force.
4. Remove MAP sensor by gently holding the connector end with one hand and pulling up on the vacuum port end until the sensor moves. Pull top side of the sensor down away from the clip and remove.
INSTALLATION
NOTE: If the MAP sensor clip is being replaced, the old clip must be removed. Use a 15 bit torx to remove and install attachment bolt.
Torque:
MAP Sensor Clip Attachment Bolt: 2.3 N.m (20 in-lbs)
NOTE: Use extreme care when inserting the MAP sensor into the sensor clip. The clip is brittle and may break if excessive force is used or if the MAP sensor is not centered when being installed.
1. Install MAP sensor first by position MAP sensor vacuum port hole is intake manifold halfway. Center sensor over clip and push sensor into clip to secure. Make sure sensor is all the way down in the intake manifold port hole.
2. Connect MAP sensor harness connector. Push in connector until a click is heard and pull back to confirm a positive engagement.
3. Install air induction tubing from throttle body to air cleaner.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
