P0190

Fuel Rail Pressure Sensor A Circuit

DTC P0190, sometimes indicated as P019000 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the air/fuel mixture causing fuel rail pressure sensor a circuit.

A Fuel Rail Pressure Sensor A Circuit is an electrical problem with the fuel rail pressure sensor that can cause the Check Engine Light to come on. The sensor measures the fuel pressure in the fuel rail, and if it fails, the fuel pressure can become too high or too low, which can cause the engine to run poorly.
If the Check Engine Light comes on, the first thing to do is to have the codes read to see what is causing the problem. If the code is P0190, the fuel rail pressure sensor may need to be replaced.
