Is the resistance less than 10,000 ohms? -> Yes REPAIR the short circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No INSTALL a new MAP sensor. Manifold Absolute Pressure (MAP) Sensor - 4.2L NA V8 - AJV8 (18.30.86) CLEAR the DTC. TEST the system for normal operation. If the DTC is repeated, refer to the warranty policy and procedures manual if an ECM is suspect. PINPOINT TEST G531332p34 : ENGINE G531332t155 : CHECK THE EFT SENSOR SENSING CIRCUIT FOR HIGH 1. Key off. 2. Disconnect the EFT sensor electrical connector, PI27. 3. Disconnect the ECM electrical connector, PI300. 4. Measure the resistance between: EFT sensor connector PI27, harness side ECM connector PI300, harness side Pin 02
Pin 46
Is the resistance greater than 5 ohms? -> Yes REPAIR the high resistance circuit. For additional information, refer to the wiring diagrams. CLEAR the DTC. TEST the system for normal operation.
-> No GO to Pinpoint Test G531332t156.
