Injector Solenoid Driver Cylinder 6 – Mechanical System Not Responding Properly or Out of Adjustment. Unintended fueling detected in cylinder Number 6.

Engine will shut down.

Fuel Injector Circuit
SMALL | MEDIUM | LARGE

Circuit Description

The electronic control module (ECM) can detect when unintended fuel injection occurs by monitoring fuel rail pressure and engine speed. This fault code is logged when the ECM determines that unintended fuel injection has occurred.

Component Location

The fuel injector is located in the cylinder head. Refer to Procedure 100-002 for a detailed component location view.

Shop Talk

This fault code can be caused by a failed or damaged injector causing continuous injection. If an injector nozzle is fractured or stuck open, continuous fueling will occur in that cylinder. If this condition occurs, an audible engine knock will be present, and the engine may stall and not
start. In addition, low fuel rail pressure and excessive exhaust smoke will be present during cranking conditions. If a failed injector is found to be the cause of this fault code, progressive damage to the combustion chamber may have occurred.
