P2302 Volkswagen Code - Ignition Coil 1 Secondary Circuit
Quick Answer
The current flow, or dwell, through the primary ignition coil is controlled by the Powertrain Control Module (PCM) by providing a switched ground path through the ignition coil driver to ground. Common causes include Faulty spark plug or coil boot, Faulty Ignition Coil 1, Ignition Coil 1 harness is open or shorted. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
