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 Replacing the engine control module (ECM)
For information about signals see Signal specification .
