Checking the connectors

Check the pressure sensor connector for intermittent contact resistance and oxidation. See Contact resistance and oxidation .

Other information

To locate the manifold absolute pressure (MAP) sensor, see Location of components
To access and replace the engine control module (ECM), see Engine control module (ECM), replacing
