Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
Engine control module (ECM) checks the signal from the boost pressure sensor which is located between the turbocharger and the throttle module.

Note! The boost pressure sensor and air temperature sensor are integrated in the same component, the boost pressure sensor.

The diagnostic trouble code (DTC) is stored if the control module detects that:
- Control signal is too low.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.
- Battery voltage higher than 10.5 V.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- Initial boost pressure or a calculated boost pressure is used.
- Fuel trim disabled.

Possible source
- Contact resistance or oxidation in the connectors.
- The signal cable is short-circuited to ground.
- The power supply cable is short-circuited to ground.
- Damaged boost pressure sensor.

Fault symptom[s]
- Malfunction indicator light (MIL), on
