Information:
This code indicates that the 5 volt supply is missing from the sensor connector.During normal engine operation, the intake manifold pressure fluctuates slightly. When the 5 volt supply is missing from the intake manifold pressure sensor, the signal from the pressure sensor floats to a midrange value. The signal does not fluctuate. If the signal from the intake manifold pressure sensor remains abnormally steady for more than 30 seconds, the Engine Control Module (ECM) activates this code.System Response:The ECM uses a default value for the intake manifold pressure.Possible Performance Effect:
Low powerTroubleshootingTest Step 1. Repair the Sensor Supply Circuit
Repair the circuit for the supply wire between the ECM and the sensor. Expected Result:The problem is resolved.Results:
OK - The problem is resolved.STOP
Not OK - The problem is not resolved.Repair: Replace the sensor.STOP
