Cylinder 11 Injector Circuit High
The P0292 code indicates that the powertrain control module (PCM) has detected a high voltage or resistance in the electrical circuit for the fuel injector on cylinder 11. This typically means the injector circuit has an open, short to voltage, or a faulty injector driver. The injector may not fire properly, causing a misfire and reduced engine performance.
01. Most Common Causes
- Faulty fuel injector on cylinder 11
- Open or shorted wiring in injector circuit
- Damaged injector connector
- Faulty PCM or injector driver
02. Symptoms You Will Notice
- Check Engine Light on
- Engine misfire or rough idle
- Reduced power and fuel economy
- Possible hesitation on acceleration
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect injector connector and wiring for damage.
Step 3: Measure resistance of injector 11; compare to spec (typically 12-16 ohms).
Step 4: Check for voltage at injector connector with key on; should see battery voltage on one pin.
Step 5: Use a noid light to test injector pulse; if no flash, check wiring and PCM output.

05. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive long distances as the misfire can damage the catalytic converter and cause poor performance.
How much does it cost to fix?▼
Repair costs vary from $150 for a simple wiring repair to $400 for injector replacement including labor.
