What Does P0192 Code Mean?

    OBD-II Code P0192 is defined as a Fuel Rail Pressure Sensor "A" Circuit Low

    The engine control module (PCM) uses a fuel rail pressure sensor to know how much pressure is going to the fuel injectors. This is so the PCM can effectively control the amount of fuel going through the fuel injectors to maintain desired power and fuel efficiency. If the PCM detects an erratic signal from the fuel pressure sensor, it will set code P0192.

    P0192 Symptoms

    • Decreased engine performance
    • Increased fuel consumption

    Common Problems That Trigger the P0192 Code

    • Powertrain Control Module (PCM) failure
    • Pressure sensor failure
    • Wiring issue
