P2288 — Injector Control Pressure Too High
P2288 — Injector Control Pressure Too High. A fault in the fuel delivery and mixture control. Short, gentle driving to a shop is usually possible. Typical causes: weak fuel pump or clogged fuel filter, vacuum or intake leaks skewing the mixture, 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 P2288 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 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 P2288 does not return.
Approximate repair cost
Repair cost depends on which component actually failed. Typical scenarios for P2288 (parts and labor, USD, independent shop rates): Replace the fuel filter: $80–$200; Replace the fuel pump: $400–$900; Clean or replace injectors: $200–$800; Replace the pressure regulator or sensor: $150–$450. Overall, fixing P2288 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 are the symptoms of P2288?
Drivers most often notice: rough idle and hesitation, increased fuel consumption, Check Engine Light on, fuel smell in severe cases.
How much does it cost to fix P2288?
Replace the fuel filter — $80–$200; Replace the fuel pump — $400–$900; Clean or replace injectors — $200–$800; Replace the pressure regulator or sensor — $150–$450. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.
What does OBD2 code P2288 mean?
P2288 — Injector Control Pressure Too High. A fault in the fuel delivery and mixture control. Short, gentle driving to a shop is usually possible. Typical causes: weak fuel pump or clogged fuel filter, vacuum or intake leaks skewing the mixture, contaminated or incorrect fuel.
How do I diagnose P2288 myself?
Start with a scan: confirm P2288, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the fuel delivery and mixture control, and verify the suspect component against live data before buying parts.
Is it safe to drive with P2288?
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 does P2288 mean?
P2288 (Injector Control Pressure Too High) is stored when self-diagnostics detect abnormal readings or behaviour of the fuel delivery and mixture control. It belongs to the powertrain (engine/transmission) category.
This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2288 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.
What causes P2288?
- contaminated or incorrect fuel
- faulty fuel pressure regulator
- weak fuel pump or clogged fuel filter
- vacuum or intake leaks skewing the mixture
Common symptoms of P2288
- rough idle and hesitation
- increased fuel consumption
- Check Engine Light on
- fuel smell in severe cases
- hard starting or long cranking
- loss of power under load
