Test NTC-9: Checking Map Sensor Operation

WARNING: This page is about a different car, the 2000 Dodge Intrepid, 2000 Chrysler LHS, 2000 Chrysler Intrepid, 2000 Chrysler Concorde, and 2000 Chrysler 300M. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For circuit identification, see WIRING DIAGRAMS article. After each repair procedure has been completed, reconnect all components. Perform TEST VER-5 to ensure system is functioning properly. Ensure no DTCs are present before performing this test.

Turn engine off. Tee a vacuum gauge to a manifold vacuum source. Start engine. Allow engine to idle. If engine will not idle, maintain a constant RPM above idle. Using scan tool, read Manifold Absolute Pressure (MAP) sensor vacuum. If scan tool vacuum reading is within one in. Hg of vacuum gauge reading, MAP sensor is functioning properly. Test is complete. If scan tool vacuum reading is not within one in. Hg of vacuum gauge reading, replace MAP sensor.
