P2322 Suzuki Code - Ignition Coil 8 Primary Control Circuit High

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 Ignition Coil 8, Ignition Coil 8 harness is open or shorted, Ignition Coil 8 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: P2322 Suzuki indicates Ignition Coil 8 Primary Control Circuit High.
Common causes: Common causes include Faulty Ignition Coil 8, Ignition Coil 8 harness is open or shorted, Ignition Coil 8 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 P2322 Suzuki 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 ground. When the ignition coil driver is switched on, 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 a feedback during the ignition diagnostics. The PCM continuously monitors the ignition system for concerns. The P2322 code sets when the PCM detects a short to voltage in the circuit.
