Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition




The engine control module (ECM) continuously detects the voltage of the rear lambda-sond (bank 2).
The engine's cylinders are counted starting with the cylinder farthest from the engine's flywheel.
If engine control module (ECM) detects that the voltage is not below or above a certain value, the engine control module (ECM) interprets this as a malfunction and generates diagnostic trouble code.
The diagnostic trouble code can be diagnosed after approx. 3-5 minutes with the engine running.

Substitute value
- Rear heated oxygen sensor control is shut off.

Possible source
- The signal cable is short-circuited to voltage.

Fault symptom[s]
