What it means
P062E is a generic code meaning the engine control unit has detected a performance fault in the fuel injector driver circuit associated with bank 2. The control unit monitors the injector driver circuitry and sets the code when the driver's feedback or behaviour does not match what it commanded. How the injector drivers are arranged and which injectors are covered depends on the engine, so check the manufacturer's data for your model.
Symptoms
- Engine warning light on
- Misfire or rough running, especially at idle
- Hesitation or reduced power under load
- Hard starting or extended cranking
- Poor fuel economy
- Engine running in limp mode on some vehicles
Possible causes
- Wiring fault in the bank 2 injector circuit (chafed, corroded, open or shorted to earth or supply)likely
- Poor connection at an injector connector or the control unit connector (corrosion, loose or spread terminals)likely
- Faulty fuel injector with a coil resistance or internal electrical fault on bank 2likely
- Low or unstable system voltage from a weak battery, poor earth or charging fault affecting the driverpossible
- Faulty injector driver inside the engine control unit or a separate injector driver modulepossible
- Outdated control unit software where the manufacturer has issued a known fix for this coderare
How to diagnose
- Read all stored and pending codes and the freeze frame data, noting engine load, temperature and battery voltage when the fault set, and look for other injector or misfire codes
- Check the battery condition and charging voltage, and inspect the main earths, as low voltage can upset injector drivers
- Visually inspect the bank 2 injector wiring, connectors and any harness routed near hot or moving parts for damage, chafing, oil contamination or corrosion
- Check the injector connectors for tight, clean terminals and correct locking
- Measure the coil resistance of each bank 2 injector and compare with the manufacturer's specification
- Check the supply and control signals at the injector connector using a suitable meter or oscilloscope during cranking or running
- Use the scan tool's active tests, if available, to operate the injectors and listen or measure for response, and compare cylinders
- Check for applicable service bulletins and software updates for the engine, and test the driver circuit at the control unit connector before suspecting the control unit
How to fix
- Repair or replace damaged wiring and renew faulty connectors or terminals in the bank 2 injector circuit
- Clean and secure loose or corroded connections, and repair poor earths
- Replace any injector that fails electrical tests, following the manufacturer's procedure, including any coding or adaptation it requires
- Restore correct system voltage by replacing a weak battery or repairing the charging system
- Repair or replace the control unit or injector driver module only after wiring and injectors are proven good, with any required programming
- Apply a manufacturer software update if one is documented for this fault
Can I keep driving?
The car may be driven carefully for a short distance, but it should be checked soon. A misfiring cylinder can overload the catalytic converter and the engine may go into limp mode. Avoid heavy loads, and stop if the engine runs very roughly or the warning light flashes.
