Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P013100

Condition
The Engine control module (ECM) measures the volume of oxygen in the exhaust gases before the three-way catalytic converter (TWC) using a front heated oxygen sensor (HO2S) (bank 1). 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 1.8 V.
- Incorrect value lasts longer than 5 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:
- Engine running for at least 2 minutes.

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
- None.

Possible source
- Contact resistance and oxidation in the terminals.
- The signal cable is short-circuited to ground.
- Open-circuit in the signal cable.
- Damaged front heated oxygen sensor (bank 1).

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