P2295
Fuel Pressure Regulator B Control Circuit Low
Fuel delivery
Generic OBD-II
High
What it means
P2295 means the ECM detects low voltage in the control circuit for the second fuel pressure regulator. Because this circuit sets fuel pressure, a fault can lead to hard starting, stalling, or power loss. A wiring short to ground or a failed regulator solenoid is the usual cause.
High
Can I keep driving? May cause hard starting, stalling, or power loss if fuel pressure is off — drive as little as possible until it's fixed.
Common symptoms
What you'll notice
- Check-engine light on
- Hard starting or intermittent stalling
- Loss of power or hesitation under load
- Rough running when fuel pressure is wrong
Common causes
Most likely first
- Faulty fuel pressure regulator 'B' (control solenoid)Likely
- Wiring shorted to ground or open in the regulator control circuitCommon
- Corroded or loose regulator connectorCommon
- ECM/PCM regulator driver faultLess often
- Related fuel-supply fault — pump or restricted line affecting pressureLess often
How to diagnose & fix
Work through it in order
- Read freeze-frame and compare commanded vs actual fuel pressure.
- Inspect the regulator connector and control wiring for shorts to ground or opens.
- Measure actual rail pressure with a gauge to confirm the regulator's behavior.
- Test the regulator solenoid resistance against spec.
- Replace the regulator if the circuit is good, then clear and re-test.
FAQ
Quick answers
Is it safe to drive with P2295?+
Not for long — incorrect fuel pressure can cause stalling or a no-start and leaves you stranded. Get it diagnosed promptly.
Can I just clear P2295?+
It returns once the ECM detects the low control circuit again. Repair the regulator or its wiring first.
