How To Replace MAP Sensor 10-17 GMC Terrain

Difficulty: Beginner · About 25 min · Gmc Terrain

Replace the manifold absolute pressure sensor on 2010–2017 GMC Terrain models by moving the intake box and engine cover for access.

Steps

1. Move the intake and cover

   With the ignition off and engine cool, loosen the intake-box clamps and detach the small hose. Remove the oil cap and lift off the engine cover, then reinstall the cap temporarily to keep debris out.

2. Remove the MAP sensor

   Release the MAP sensor connector lock and unplug the harness. Remove the sensor’s retaining screw and pull the sensor straight from its mounting point.

3. Install the replacement

   Seat the new sensor squarely and reinstall its fastener, tightening only to the vehicle specification. Reconnect the harness until its lock clicks into place.

4. Reassemble the intake

   Remove the oil cap, refit the engine cover on its locating points, and reinstall the cap. Seat the intake box and attached hoses fully, tighten both clamps, and reconnect the smaller hose.

5. Check operation

   Inspect the intake joints and sensor plug before starting the engine. Confirm the engine runs normally and check for warning lights; further diagnosis may be needed if a fault remains.

Check your vehicle’s repair manual for exact specifications and fit.
