Diagnosis Procedure
- CHECK MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR POWER SUPPLY CIRCUIT-I
- Disconnect manifold absolute pressure (MAP) sensor harness connector.
- Turn ignition switch ON.
- Check the voltage manifold absolute pressure (MAP) sensor harness connector and ground.
Manifold absolute pressure (MAP) sensor Ground Voltage (V) Connector Terminal F19 1 Ground Approx. 5 Is the inspection result normal?
YES: GO TO 2.
NO: Repair open circuit, short to ground in harness or connectors.
- CHECK MANIFOLD ABSOLUTE PRESSURE (MAP) SENSOR GROUND CIRCUIT FOR OPEN AND SHORT
- Turn ignition switch OFF.
- Disconnect ECM harness connector.
- Check the continuity between manifold absolute pressure (MAP) sensor harness connector and ECM harness connector.
