Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P009700

Condition
Engine control module (ECM) checks the signal from the air temperature sensor (integrated in 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 control module checks the direct voltage from the sensor.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- The direct voltage is lower than 0.112 V.
- Incorrect value lasts longer than 9 seconds.
- Incorrect value lasts for 2 or more subsequent driving cycles.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition switch position II.

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
- Value from the engine intake air temperature (IAT) sensor in the intake manifold is used.
- Fuel trim disabled.

Possible source
- Contact resistance and oxidation in the terminals.
- Short-circuit to ground in the signal cable.
- Open-circuit in the signal cable.
- Damaged air temperature sensor (integrated in boost pressure sensor).

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