Read the data of atmospheric absolute pressure signal using Vehicle Diagnostic Interface.
NOTE:
- Vehicle Diagnostic Interface
For detailed operation procedure, refer to the "READ CURRENT DATA FOR ENGINE ".
Is the measured value more than 13.3 kPa (100 mmHg, 3.94 inHg) by shaking the harness and connector of ECM?
YES
Repair poor contact in ECM connector.
NO. Go to CHECK HARNESS BETWEEN MANIFOLD ABSOLUTE PRESSURE SENSOR & ECM CONNECTOR .
