P0292 medium Severity

P0292: Cylinder 11 Injector Circuit High

Check Engine Light illumination, possible misfire, rough idle, and reduced engine performance

Overview

OBD‑II DTC P0292 indicates a high voltage condition in the fuel injector circuit for cylinder 11, often caused by wiring faults, faulty injector, or injector driver issues in the PCM.

Common Symptoms

  • Check Engine Light (CEL) illuminated during drive
  • Rough idle or engine running unevenly
  • Misfire specific to cylinder 11
  • Reduced fuel economy and loss of power

Most Common Causes

Faulty or internally shorted fuel injector on cylinder 11 high

Shorted coil or internal failure increases circuit current draw beyond expected range.

Damaged, corroded, or poorly connected wiring/connector in injector 11 circuit high

Harness issues can cause high resistance or voltage anomalies in the injector circuit.

PCM injector driver transistor failure medium

High output from the driver due to internal failure can mimic high circuit voltage.

Incorrect interpretation from some sources claiming turbo overboost low

Certain sites incorrectly list P0292 as a turbo overboost code, but generic references consistently describe injector circuit high.

Diagnostic Steps

  1. Connect a professional OBD‑II scanner and verify code P0292 and any related misfire codes
    Expected: Code P0292 present, possibly with P03xx misfire codes
    Interpretation: Confirms circuit high condition and potential misfire in cylinder 11.
  2. Inspect the wiring harness and connector for cylinder 11 injector for corrosion, pin damage, or loose connections
    Expected: No chafing, corrosion, or loose terminals
    Interpretation: Damaged wiring can cause high resistance and abnormal circuit readings.
  3. Measure fuel injector 11 resistance with a multimeter
    Expected: Resistance within manufacturer spec for that injector
    Interpretation: Out‑of‑spec resistance suggests a short or open circuit in the injector.
  4. Perform PCM injector driver test with advanced scan tool if available
    Expected: Normal voltage cycling at driver output
    Interpretation: Abnormal driver signals indicate a PCM driver fault rather than injector/wiring issue.

Repair Solutions

Replace defective fuel injector on cylinder 11 medium
Estimated Cost: $250 - $600

Injector cost varies by vehicle; include labor for removal and installation.

Repair or replace damaged wiring and connectors for injector circuit medium
Estimated Cost: $50 - $200

Cost reflects typical harness repair/replacement and connector cleaning.

Replace PCM if injector driver circuit is confirmed faulty hard
Estimated Cost: $400 - $1200

PCM replacement and programming required; costs vary widely by vehicle.

Common Misdiagnoses

Avoid these common diagnostic mistakes:

  • Misidentifying P0292 as a turbo boost/overboost code (common on generic DTC sites)

Frequently Asked Questions

Technical definition of P0292 OBD-II Code

Technically, the P0292 code represents Cylinder 11 Injector Circuit High. It usually points to a fault within the Fuel System.

Reflecting on severity: How bad is P0292?

The P0292 code is considered medium severity. Check Engine Light illumination, possible misfire, rough idle, and reduced engine performance

Symptoms associated with DTC P0292

You may experience the following: Check Engine Light (CEL) illuminated during drive, Rough idle or engine running unevenly, Misfire specific to cylinder 11.

Common triggers for the P0292 error

It can be caused by several factors, most notably: Faulty or internally shorted fuel injector on cylinder 11, Damaged, corroded, or poorly connected wiring/connector in injector 11 circuit, PCM injector driver transistor failure.

Estimated repair costs for different causes of P0292

It depends on what needs to be fixed. Repair or replace damaged wiring and connectors for injector circuit repairs are cheaper (~$200), while Replace PCM if injector driver circuit is confirmed faulty repairs are on the higher end (~$1200).

Does P0292 affect Ford, Toyota, or Honda?

The P0292 code is a generic powertrain code, meaning it applies to almost all makes and models, such as Honda, Toyota, VW, Ford, and Chevy.
