Replace the manifold absolute pressure sensor on 2010–2016 Cadillac SRX models after identifying the correct sensor and connector for the engine.

Steps

1. Remove the engine cover

   Switch off the ignition and remove the engine-cover fastener. Remove the oil cap, lift the cover away, and immediately reinstall the cap to keep debris out of the engine.

2. Remove the MAP sensor

   Unplug the sensor connector by releasing its locking tab. Remove the sensor retaining screw and lift the sensor straight out of its mounting point.

3. Install the replacement sensor

   Seat the replacement sensor fully in its mount and install its screw without overtightening. Reconnect the wiring plug and confirm the connector lock is engaged.

4. Refit the cover and test

   Remove the oil cap again, position the engine cover, and secure its fastener. Refit the oil cap, then start the engine and check for a warning light or continuing drivability problem.

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