How to replace the MAP Sensor on Buick Lucerne?

Starting the Manifold Absolute Pressure Sensor replacement requires removing the intake manifold cover. Begin by disconnecting the engine harness electrical connector from the MAP sensor then carefully remove the locking tabs before you can take out the sensor. Install the new MAP sensor by first checking the installation seal for proper condition before both positioning the sensor correctly and engaging its locking tabs. First reconnect the engine harness electrical connector to the MAP sensor before putting back the intake manifold cover.

How to service the MAP Sensor on Buick LeSabre?

Begin servicing the manifold absolute pressure (MAP) sensor with a first step to switch off the ignition and remove the fuel injection sight shield. The pcv valve cover now requires disconnecting the MAP Sensor's electrical connection to perform service. Gently deforming the locking tabs which binds the MAP Sensor to the pcv valve cover allows sensor removal before extracting the MAP Sensor directly from the pcv valve cover. During installation check that both the MAP Sensor seal and component remain intact. Apply the MAP Sensor to the pcv valve cover by verifying that locking tabs connect correctly to protect the sensor. Complete your installation by connecting and securing the MAP Sensor electrical connector followed by putting back the fuel injection sight shield.

How to service the MAP Sensor on Buick Regal?

Start servicing the Manifold Pressure/Vacuum Sensor by taking off the fuel injector sight shield first. As the next step remove the vacuum hose and electrical connector from the MAP sensor while you unscrew the manifold absolute pressure sensor screws to extract the MAP sensor. Begin by fastening the MAP sensor to its position and then fix it with MAP sensor screws according to the Fastener Notice in Service Precautions by tightening them to 5 N.m (44 lb in). Reinstall the fuel injector sight shield once all steps are complete.
