Cylinder 10 Injector Circuit Range/Performance
The P02F7 code indicates that the Engine Control Module (ECM) has detected a malfunction in the electrical circuit of the fuel injector for cylinder 10. This could be due to an open or short circuit, or the injector's performance is outside the expected range, affecting fuel delivery and combustion.
01. Most Common Causes
- Faulty fuel injector on cylinder 10
- Open or shorted wiring in the injector circuit
- Poor electrical connection at the injector connector
- Failed ECM (rare)
02. Symptoms You Will Notice
- Engine misfire on cylinder 10
- Rough idle or hesitation
- Check Engine Light illuminated
- Decreased fuel economy
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect the injector connector and wiring for damage.
Step 3: Use a multimeter to test injector resistance (typically 11-18 ohms).
Step 4: Perform a injector balance test or power balance test to confirm injector performance.
Step 5: Check for voltage and ground at the injector connector with the engine running.
