P062E: Fuel Injector Driver Circuit Performance Bank 2
The P062E code indicates a performance issue in the fuel injector driver circuit for Bank 2. This circuit controls the electrical signal to the fuel injectors on that bank. The powertrain control module (PCM) has detected that the actual voltage or current in the circuit does not match the expected values, which can cause improper fuel delivery, leading to misfires, poor fuel economy, and potential engine damage if not addressed.
01. Most Common Causes
- Faulty fuel injector driver module
- Shorted or open wiring in the injector circuit
- Failed fuel injector on Bank 2
- Corroded or loose electrical connectors
- PCM failure (rare)
02. Symptoms You Will Notice
- Check Engine Light illuminated
- Engine misfire or rough idle
- Poor acceleration or hesitation
- Decreased fuel economy
- Possible engine stalling
03. Step-by-Step Diagnosis
Step 1: Scan for codes and record freeze frame data.
Step 2: Visually inspect wiring and connectors for Bank 2 injectors for damage or corrosion.
Step 3: Test injector driver circuit voltage and resistance with a multimeter.
Step 4: Perform a injector balance test or flow test to isolate faulty injector(s).
Step 5: Check the fuel injector driver module if equipped.
