P0192 on 2007-2012 MINI Cooper S — Fuel Rail Pressure Sensor Circuit Low Input
1 vehicles · 1 makes · $500-$1,200 repair
Most Reported On
P0192 is an OBD-II diagnostic trouble code meaning “Fuel Rail Pressure Sensor Circuit Low Input.” This code means the fuel rail pressure sensor is reporting an abnormally low voltage to the computer, lower than the valid operating range. This sensor measures the pressure of fuel in the high-pressure rail feeding the injectors, which the computer uses to control fueling precisely. A low signal usually points to an electrical fault (such as a short to ground or open circuit) rather than genuinely low fuel pressure, though the two can look similar. You may notice hard starting, rough running, reduced power, or a no-start. This code is most commonly reported on 2007-2012 MINI Cooper S, with repair costs ranging from $500 to $1,200.
