Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P013700

Condition




The engine control module (ECM) assumes two initial values for probe voltage, 0 V and 5 V.
If probe preheating is active and if at least one fuel shut-off (accelerator pedal released for at least 3 seconds) has been made, the rear heated oxygen sensor (bank 1) maximum value must have exceeded 0.6 V and the minimum value must have been below 0.1 V.
The engine cylinders are counted from the cylinder furthest away from the flywheel.
The diagnostic trouble code (DTC) is stored and the engine control module (ECM) interprets it as a fault if these parameters are not achieved after approximately 5 minutes and both the accumulated and actual heated oxygen sensor preheating have reached certain parameters.
The diagnostic trouble code (DTC) can be diagnosed when the engine is running.

Substitute value
- Rear heated oxygen sensor (HO2S) control shut off.

Possible source
- The signal cable is short-circuited to ground.
- Open-circuit on the signal cable.
- Damaged rear heated oxygen sensor (HO2S).

Fault symptom[s]
- Malfunction indicator lamp (MIL) lit.
