OBD-II (EN): Manufacturer Specific - Brake Regeneration or Ignition System Out of Range

Code P3370 is a manufacturer-specific error indicating incorrect operation of the drivetrain system – it may concern the ignition system, misfire (rough engine operation), or the brake energy regeneration system in hybrid vehicles. Causes may include electrical faults, damaged sensors, or ignition system components. We recommend an immediate visit to a mechanic with appropriate diagnostic equipment to precisely locate the source of the problem.

Symptoms

Check Engine or MIL lights on the dashboard; possible jerking or vibration of the vehicle while driving; reduced engine or drivetrain efficiency; possible problems with energy recovery during braking (in hybrid/electric vehicles); sporadic ignition errors or rough engine operation.

Possible causes

• Damaged or worn brake regeneration control module (in hybrid/EV vehicles) • Fault in the ignition coil or spark plug causing incorrect combustion • Damaged wiring or electrical connectors leading to the ECU/PCM module • Incorrect readings from wheel speed sensors or brake system sensors • Fault in the inverter or kinetic energy recovery system
