Cylinder 6 Injector Circuit Range/Performance
The P02F3 code indicates that the Engine Control Module (ECM) has detected a range or performance issue in the electrical circuit of the fuel injector for cylinder 6. This could be due to abnormal resistance, voltage, or current in the injector circuit, affecting fuel delivery and combustion efficiency.
1. Most Common Causes
- Faulty fuel injector on cylinder 6
- Open or shorted wiring in injector circuit
- Poor electrical connection at injector or ECM
- Failed ECM (rare)
2. Symptoms You Will Notice
- Engine misfire on cylinder 6
- Rough idle or hesitation
- Decreased fuel economy
- Check Engine Light illuminated
3. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Inspect wiring and connectors for damage or corrosion.
Step 3: Test injector resistance with a multimeter (specs: 11-16 ohms).
Step 4: Swap injector with another cylinder to see if code follows.
Step 5: Check for power and ground at injector connector with a test light.
