P2323 DODGE - Ignition Coil 'H' Secondary Circuit
P2323 DODGE Possible Causes
- Faulty Ignition Coil 'H'
- Ignition Coil 'H' harness is open or shorted
- Ignition Coil 'H' circuit poor electrical connection
Cost of diagnosing the P2323 DODGE code
The cost of diagnosing the P2323 DODGE code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
P2323 DODGE Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine may be running rough
P2323 DODGE Meaning
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 P2323 code sets when the PCM
detects a short to voltage in the circuit.
