Circuit Description
The injection pump delivers fuel to the individual cylinders by opening and closing a solenoid control fuel valve. The PCM monitors the amount of time it takes for the fuel solenoid valve to physically close after commanded to close. Any closure time that is out of range is seen as a fault. This response time is measured in milli seconds. This is a type D DTC.

Conditions for Setting the DTC

^ The battery voltage is greater than 10 volts and less than 16 volts.
^ The engine coolant temperature is greater than -1°C (34°F).
^ The ENGINE SPEED is greater than 506 RPM.
^ The requested fuel rate is greater than 0.0 mm
^ The closure time is greater than 2.5 ms.

Action Taken When the DTC Sets
A possible poor performance.

Conditions for Clearing the MIL/DTC

^ A History DTC will clear after forty consecutive warm-up cycles during which the diagnostic does not fail (the coolant temperature has risen 5°C (40°F) from the start up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) during that same ignition cycle).
^ Use of a Scan tool will clear the DTC codes.

Diagnostic Aids
A weak (mechanical failure) fuel solenoid will result in a DTC P1217. If DTC P1217 is set with any other DTCs, diagnose them first. If the vehicle is running close to the DTC setting closure time, the vehicle should be checked during cold start ups and during hot conditions. Poor performance and starting conditions will exist. Fuel contamination could also cause this DTC.

Test Description
The number(s) below refer to the Step number(s) on the Diagnostic Table.

3. This Step determines if DTC P1217 is a hard failure or an intermittent.
6. This Step will determine if the solenoid is malfunctioning, or if there is a problem with the PCM or wiring.
