Code P0193 2002 Ford F150 Description

The P0193 code for a 2002 Ford F150 indicates a Fuel Rail Pressure Sensor Circuit High Input. This means that the powertrain control module (PCM) has detected a higher than normal voltage signal from the fuel rail pressure sensor. The fuel rail pressure sensor is responsible for monitoring the fuel pressure in the fuel rail and sending this information to the PCM. When the sensor detects a high input signal, it can lead to various issues with the vehicle's performance.

Tech Notes for P0193 2002 Ford F150

The comprehensive component monitor (CCM) monitors the FRP sensor circuit to the PCM for high voltage. If voltage were to fall below a calibrated limit and a calibrated amount of time during testing, the test will fail.

A FRP PID value during KOER or KOEO less than 0.3 volts for gasoline or 0.5 volts for natural gas vehicles (NG) would indicate a hard fault.
