What P2295 means
P2295 stands for the control line of fuel pressure regulator B touching ground. GM's 2018 diesel ECM detects it with its low-side driver switched off: if the measured voltage corresponds to 0.5 Ω or less towards ground, the sample counts as failed, and 44 of 88 samples at 6.25 ms confirm the fault as Type B. VW's 2014 Passat quick reference describes the same fault as a ground short, with a signal voltage below 1.40 V. Chafed insulation near the rail or pump, water in the connector and a shorted valve coil are typical findings. Because a grounded low-side line can keep the valve energised regardless of command, rail pressure may drift from target and the ECM may reduce power. P2296 is the high counterpart.
P2295 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2295
- Check engine light
- Rail pressure too high or unstable, reduced power
- Rough running
Common causes of P2295
- Most likelyControl wire chafed through to ground
- PossibleWater or corrosion in the regulator connector
- PossibleShorted coil in the pressure regulator valve
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2295 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 2 | Area: fuel and air metering (injector circuit). |
| 95 | The exact fault in that area. |
What to do next
- Note P2295 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2295
What does P2295 mean?
P2295 means "Fuel Pressure Regulator B Control Circuit Low". P2295 stands for the control line of fuel pressure regulator B touching ground. It is a generic code, so it means the same on every make.
Is it safe to drive with P2295?
Drive gently and only to a workshop. With P2295 the car can go into limp mode (reduced power) to protect itself.
Will P2295 fail an emissions test?
Yes, it can. P2295 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2295 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P2295 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
