Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information ECM-P227100

Condition

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.
