Diagnostic Trouble Code (DTC) Information

ECM-P015600 Heated Oxygen Sensor (HO2S) Circuit (Bank 2, Sensor 2)

Condition







Engine Control Module (ECM) measures the voltage difference between the rear heated oxygen sensor's (bank 2) max. value and min. value, and the difference must be greater than 0.3 V.

The engine cylinders are counted from the cylinder furthest away from the flywheel.

- Bank 1 (cylinder row nearest the front): cylinders 1, 3, 5 and 7.
- Bank 2 (cylinder row furthest to the rear, nearest the passenger compartment): cylinders 2, 4, 6 and 8.

The diagnostic trouble code (DTC) is stored if the engine control module (ECM) registers that these parameters are not reached after approximately 5 minutes and the accumulated or actual probe preheating has reached its parameter.

The diagnostic trouble code (DTC) can be diagnosed approximately 5 minutes after starting (if probe preheating is active and at least one fuel shut-off has been made for at least 3 seconds).

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

Possible Source
- Contact resistance or oxidation in the terminals
- Damaged rear heated oxygen sensor (HO2S).

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