Fuel Injector Driver Circuit Performance Bank 2
The P062E code indicates a performance issue in the fuel injector driver circuit for Bank 2 (the side of the engine not containing cylinder #1). This circuit controls the electrical signals that open and close the fuel injectors. When the powertrain control module (PCM) detects that the actual performance of the injector driver circuit does not match the expected performance, it sets this code. This can be caused by a faulty injector driver module, wiring issues, or a defective PCM.
1. Most Common Causes
- Faulty injector driver module inside the ECM/PCM
- Wiring or connector issues in the Bank 2 injector control circuit
- Excessive resistance in the injector driver circuit
- Internal failure of one or more Bank 2 fuel injectors
- ECM/PCM software update required
- Poor ground in the injector circuit
2. Symptoms You Will Notice
- Engine misfire or rough idle
- Check Engine Light illuminated
- Poor fuel economy
- Engine hesitation or stalling
3. Step-by-Step Diagnosis
Step 1: Use a scan tool to retrieve all codes and freeze frame data.
Step 2: Visually inspect the wiring and connectors for Bank 2 injectors for damage or corrosion.
Step 3: Test the fuel injector driver circuit with a multimeter for proper voltage and ground.
Step 4: Check the fuel injector resistance and compare to specifications.
Step 5: If wiring and injectors are good, suspect the PCM or driver module.
4. Frequently Asked Questions
Is it safe to drive with this code?▼
It is not recommended to drive with this code as it can cause engine misfires, reduced performance, and potential damage to the catalytic converter.
How much does it cost to fix?▼
The cost typically ranges from $150 to $400, depending on whether the issue is wiring, a driver module, or PCM replacement.
