To change the Manifold absolute pressure Sensor, you need to remove the fuel injector sight shield. Remove the manifold absolute pressure sensor on the engine wiring harness electrical connector from MAP sensor, then pull out the MAP sensor bolt as well as the sensor. Apply clean engine oil to the NEW MAP sensor O-ring seal and install the MAP sensor and bolt, securing the bolt to 10 N.m (89 lb in). Then, connect the MAP sensor to the engine wiring harness electrical connector and reinstall the fuel injector sight shield.
