P2295 — Fuel Pressure Regulator 2 Control Circuit Low
P2295 — Fuel Pressure Regulator 2 Control Circuit Low. A fault in the fuel delivery and mixture control. Short, gentle driving to a shop is usually possible. Typical causes: vacuum or intake leaks skewing the mixture, weak fuel pump or clogged fuel filter, contaminated or incorrect fuel.
powertrain (engine/transmission)
Is it safe to drive?
Drive with caution Drive with caution. Mixture and fuel-pressure faults can cause stalling, hesitation in traffic and — when severe — catalyst damage. Avoid long trips until diagnosed.
How to diagnose with an OBD scanner
- Read the code and freeze frame Connect an OBD2 scanner, confirm P2295 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
- Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
- Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the fuel delivery and mixture control for damage, corrosion, chafing or poor contact.
- Subsystem check Check for supply voltage at the fuel pressure regulator 2 control connector first; then measure resistance from the signal wire to ground — near-zero ohms confirms a short to ground in the harness.
- Subsystem check Measure fuel pressure at the rail and compare with factory specification at idle and under load.
- Subsystem check Check short-term and long-term fuel trims in live data to see which way the mixture is off.
- Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2295 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2295 (parts and labor, USD, independent shop rates): Replace the fuel filter: $80–$200; Replace the pressure regulator or sensor: $150–$450; Clean or replace injectors: $200–$800; Replace the fuel pump: $400–$900. Overall, fixing P2295 usually costs between $80 and $900. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.
Common questions
What is the most common cause of P2295?
The most common causes are: vacuum or intake leaks skewing the mixture, weak fuel pump or clogged fuel filter, contaminated or incorrect fuel.
Is it safe to drive with P2295?
Drive with caution. Mixture and fuel-pressure faults can cause stalling, hesitation in traffic and — when severe — catalyst damage. Avoid long trips until diagnosed.
What are the symptoms of P2295?
Drivers most often notice: increased fuel consumption, hard starting or long cranking, fuel smell in severe cases, Check Engine Light on.
How do I diagnose P2295 myself?
Start with a scan: confirm P2295, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the fuel pressure regulator 2 control, and verify the suspect component against live data before buying parts.
How much does it cost to fix P2295?
Replace the fuel filter — $80–$200; Replace the pressure regulator or sensor — $150–$450; Clean or replace injectors — $200–$800; Replace the fuel pump — $400–$900. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
What does P2295 mean?
Behind P2295 is a specific failure in the fuel delivery and mixture control: fuel pressure regulator 2 control circuit low. The onboard computer stores it in the powertrain (engine/transmission) group after verifying the fault over repeated checks.
“Circuit low” means the voltage on the fuel pressure regulator 2 control circuit stays below the expected minimum — close to ground. The usual physical reasons are a short to ground, a chafed wire touching metal, a missing supply voltage, or a failed component dragging the signal down.
To set P2295, the control module compares live readings of the fuel delivery and mixture control against calibrated limits, usually over several drive cycles. Alongside the code it stores a freeze frame — a snapshot of rpm, load, coolant temperature and vehicle speed at the moment of failure. Reading that snapshot first saves diagnostic time.
What causes P2295?
- failed fuel pressure regulator 2 control pulling the signal low
- signal wire shorted to ground (chafed insulation)
- missing supply voltage to the fuel pressure regulator 2 control
- clogged or leaking fuel injectors
- faulty fuel pressure regulator
- vacuum or intake leaks skewing the mixture
- weak fuel pump or clogged fuel filter
- faulty fuel rail pressure sensor or wiring
Common symptoms of P2295
- increased fuel consumption
- hard starting or long cranking
- fuel smell in severe cases
- Check Engine Light on
- loss of power under load
- rough idle and hesitation
