Circuit Description

WARNING: This page is about a different variant/trim than selected.

Injection pump delivers fuel to individual cylinders by opening and closing a solenoid control fuel valve. PCM monitors amount of time fuel solenoid valve physically takes to close after being commanded to close. Fault will occur if closure time out of range. Response time is measured in milliseconds.

DTC will set when the following conditions are present:

Battery voltage is greater than 10 volts but less than 16 volts.
Engine coolant temperature is greater than 122°F (50°C).
Engine speed is greater than 1350 RPM.
Requested fuel rate is greater than 0.0 mm.
Injection pump closure time is less than .75 milliseconds.
