2018年1月16日 · OBD II fault code P2539 is a generic code that is defined as “Fuel low pressure sensor – circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects a general failure of, or malfunction in the control circuit of the low-pressure side of the fuel system, or in the fuel low-pressure sensor itself.

2024年4月4日 · P2539 indicates a low voltage problem in the fuel pressure sensor circuit. Symptoms include the engine warning light, poor performance, difficulty starting, stalling, reduced fuel economy, and rough idling. Causes range from a faulty fuel pressure sensor to wiring issues, bad connections, a faulty fuel pump, a clogged fuel filter, or ECM problems.

What are the possible causes of the automobile fault code P2539? If you see the engine light on or the service engine soon warning light, it could be due to the P2539 fault code. This code is usually caused by a low fuel level, faulty low-pressure fuel system sensor, or a poor electrical connection in the low-pressure fuel system sensor circuit.
