P2295 indicates that the fuel pressure regulator (fuel pressure regulator B) is operating at a lower pressure than expected according to the engine control module. The problem is detected by a low‑pressure signal in the regulator’s control circuit.
The regulator itself can wear out or become stuck in the low‑pressure position, causing a persistent low‑pressure reading.
A short or degraded wiring harness, connector, or fuse can lower the voltage seen by the PCM.
A pump that cannot maintain proper pressure may trigger a low‑pressure signal to the regulator.
An unintended vacuum source or blockage can reduce fuel pressure, mimicking a regulator fault.
In rare cases, a software glitch could misread the regulator’s signal, but this is uncommon.
No, most cases are due to the regulator itself or its electrical circuit. Replacing the PCM is rarely necessary.
It can be done, but you may experience reduced performance and fuel economy. It is advisable to address the issue before extended operation.
No, a high pressure reading would trigger a different code. P2295 specifically indicates a low pressure condition.
