Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P007300

Condition
Engine control module (ECM) measures the ambient temperature using an outside temperature sensor. The sensor is located in the left external rear-view mirror. 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 higher than 4.951 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
- The control module uses a constant outside temperature, +20 °C.

Possible source
- Open-circuit in signal cable or ground lead.
- Contact resistance and oxidation in the terminals.
- Short-circuit to supply voltage in the signal cable.
- Damaged outside temperature sensor.

Fault symptom[s]
- Warning lights and chimes/Malfunction Indicator Light ("Check engine" light) indication/no indication
