Should you fix P2323 yourself?

Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.

What causes OBD-II fault code P2323?

The ignition coil or coils are responsible for igniting the air/fuel mixture inside the combustion chambers. Without reliable performance from the ignition coil(s) the vehicle will stumble and misfire. The engine control module (PCM) has special transistors called "drivers" to turn the Ignition Coil(s) on an off. If the PCM cannot control the Ignition Coil, it will set code P2323.
