P0190 on MINI
Fuel Rail Pressure Sensor Circuit Malfunction
P0190 on MINI vehicles indicates fuel rail pressure sensor circuit malfunction. Au7o has documented this code across 1 MINI model — most commonly on Cooper S. P0190 indicates a malfunction in the fuel rail pressure sensor circuit. This sensor measures the pressure of fuel in the rail (common on direct-injection and high-pressure systems) and reports it to the PCM, which uses it to control the fuel pump and injectors for precise fueling. The code sets when the sensor's signal is out of range, erratic, or electrically faulty. Symptoms can include hard starting, stalling, hesitation, reduced power, or the engine going into a reduced-power fail-safe mode. Typical repair costs on MINI range from $500 to $1,200, depending on the specific model and root cause.
Common Causes of P0190
- •Faulty fuel rail pressure sensor
- •Damaged wiring or connector at the sensor
- •Corroded or loose connector terminals
- •Open, short, or poor ground in the sensor circuit
- •Reference voltage problem from the PCM
- •Actual fuel pressure problems (pump/regulator) confusing the sensor
- •Failed PCM input (rare)
P0190 on MINI by Model
MINI Cooper S(1 issue)
- High-Pressure Fuel Pump (HPFP) Failure2007-2012
The N14 engine's high-pressure fuel pump (same issue as early BMW N54) fails prematurely, causing long cranking, rough running, and stalling. The internal cam follower wears down, reducing fuel pressure to the direct injection system.

What does P0190 mean on MINI?▼
P0190 stands for "Fuel Rail Pressure Sensor Circuit Malfunction." P0190 indicates a malfunction in the fuel rail pressure sensor circuit. This sensor measures the pressure of fuel in the rail (common on direct-injection and high-pressure systems) and reports it to the PCM, which uses it to control the fuel pump and injectors for precise fueling. The code sets when the sensor's signal is out of range, erratic, or electrically faulty. Symptoms can include hard starting, stalling, hesitation, reduced power, or the engine going into a reduced-power fail-safe mode. On MINI specifically, this code is documented across 1 model.
What causes P0190 on MINI vehicles?▼
Common causes on MINI: Faulty fuel rail pressure sensor, Damaged wiring or connector at the sensor, Corroded or loose connector terminals, Open, short, or poor ground in the sensor circuit, Reference voltage problem from the PCM.
