About P117E

P117E is a manufacturer-specific powertrain diagnostic trouble code recorded for Ford vehicles. It belongs to the P-prefix family of codes, which covers engine, transmission, emissions, or fuel-system faults.

Scanning & clearing: A generic OBD-II scan tool will usually read and clear powertrain (P) codes. For live data, freeze-frame capture, and bi-directional tests you may need a more capable scan tool that supports the vehicle's ECM protocol.

P117E is a manufacturer-specific code. The same code string on a different make may have a different meaning. Always confirm the code's definition against the vehicle's service information for the specific make and model under test.

Code Information

The PCM monitors the fuel volume regulator, the metering valve that controls fuel delivery into the high pressure pump, to regulate fuel rail pressure. DTC P117E is set when the PCM commands the fuel volume regulator to its minimum control limit, typically near zero duty cycle, but the measured fuel rail pressure remains higher than the desired target. This indicates the system cannot reduce rail pressure despite minimum control effort, which can cause rough running, smoke, hard starting, or pressure related driveability faults. The cause usually lies in a regulator stuck open, a restricted re...
