FAULT CODE 276
Injection Control Valve Stator Circuit

CODE REASON EFFECT
Fault Code: 276
PID: S018
SPN: 633
FMI: 5
LAMP: Yellow
SRT:
High current detected on injection control valve stator return pin 7.

Engine power derate. Engine possibly dies.

Circuit Description

The injection control valve regulates both the quantity of fuel that is injected into each cylinder and the timing of the injection event. The injection control valve stator is the electronic solenoid that actuates the injection control valve. The engine control module (ECM) commands the stator to actuate the injection control valve to open based on several different parameters, including fuel pressure, engine speed, and throttle position.

Component Location

The injection control valve is located on the fuel injection pump on the top of the distributor. The injection control valve stator is mounted onto the front side of the injection control valve with four capscrews.

Shop Talk

This fault code can be caused by a faulty stator, improper or poor grounds, and internal damage to the injection control valve. Inspect the snapshot data to see if the battery voltage dropped below 9-VDC when the fault code logged. In addition to these possible causes, a malfunctioning transient suppressor can also cause Fault Code 276 to become active, and is often accompanied with an engine no-start condition. If these symptoms occur, replace the transient suppressor.

A damaged injection control valve may also damage the transient suppressor and/or the ECM. Trying to start the engine with a damaged ECM and/or transient suppressor can cause damage to the injection control valve.
