Causes and Fixes P0192 Code: Fuel Rail Pressure Sensor “A” Circuit Low

How to fix P0192 Code: Fuel Rail Pressure Sensor “A” Circuit Low A P0192 code is set when the computer detects the fuel rail pressure sensor (FPCM) is not within a specified range. It is best to get a diagram or schematics for the vehicle since there are differences in wire color, sensor location, and how many sensors there are. Wiring to an FPCM sensor is usually 5-volts, ground, and signal wire to the computer. Possible Causes of a P0192 Code: Wiring Issue Open - Short Blown Fuse - Bad Relay Bad Fuel Pressure Sensor Bad Computer (PCM/FPCM) By using this information, the user assumes all risks of use.
