P2302 Mitsubishi Code - Ignition Coil 1 Secondary Circuit Insufficient Ionization

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 the ground. Common causes include Faulty Ignition Coil 1, Ignition Coil 1 harness is open or shorted, Ignition Coil 1 circuit poor electrical connection. 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.

What it means: P2302 Mitsubishi indicates Ignition Coil 1 Secondary Circuit Insufficient Ionization.
Common causes: Common causes include Faulty Ignition Coil 1, Ignition Coil 1 harness is open or shorted, Ignition Coil 1 circuit poor electrical connection.
Severity: High - diagnose this code as soon as possible.
Can I drive?: Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2302 Mitsubishi Description

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 the ground. When the ignition coil driver is switched on, the current rapidly builds up to a maximum value, determined by the coil inductance and resistance. When the current is switched off, the magnetic field collapses which induces a secondary high voltage surge, and the spark plug is fired. This high voltage surge creates a flyback voltage which the PCM uses as feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2302 code sets when the PCM detects a short to voltage in the circuit.
