P2325 code definition

The P2325 code being stored means that an ignition coil (or more than one) experienced problems with its primary or secondary circuit.

What the P2325 code means

The vast majority of modern vehicles rely on a “coil on plug” system to produce the necessary spark for getting the engine to work. If a vehicle is modern enough to be outfitted with a Powertrain Control Module (PCM), it’s a safe bet that it uses this kind of system. There are about 35 other codes related to P2325, which means you’ll often find a number of them being stored at the same time.

They all have to do with circuitry problems related to an ignition coil. These ignition coils are located atop the ignition plug in a vehicle and is powered by electricity through the PCM. It’s this electricity that creates the spark the spark plugs need for ignition. This required spark and the ignition’s timing are both initiated by a voltage signal from a ground signal and the battery. The manufacturer of the vehicle set an acceptable voltage range for the ignition coil. If the voltage gets outside of this range – in either direction – the PCM will log a P2325 code, which means something is wrong with ignition coil “I.”

What causes the P2325 code?

There are a handful of potential causes that could be behind the P2325 code. Here are the most common ones you’ll want to know about:

  • The ignition coil connector has corroded or become damaged
  • The ignition coil wiring is shorted, frayed or broken
  • The fuel injector is no longer working correctly
  • The ignition coil is broken
  • A spark plug is no longer working correctly Of course, there’s always the possibility that the PCM has become faulty, but this explanation is only worth exploring if nothing else fits.

What are the symptoms of the P2325 code?

Aside from the Check Engine Light coming on, the following symptoms would accompany the P2325 code:

How does a mechanic diagnose the P2325 code?

The following steps will need to be taken to diagnose this problem:

  • An OBD-II scanner is necessary to pull which codes have been stored by the PCM.
  • Any camshaft or crankshaft sensor trouble codes will need to be addressed.
  • Any misfire trouble codes will need to be addressed next.
  • The ignition coil wiring must be put through an inspection
  • Wiring and connectors will need to be inspected and replaced as necessary

Common mistakes when diagnosing the P2325 code

Don’t make the mistake of inspecting the ignition coil wiring and/or connectors before replacing ignition coils and/or spark plugs as necessary. If the latter two components are experiencing problems, doing the former won’t make a difference where the P2325 code is concerned.

How serious is the P2325 code?

Though there are worst things that could happen to a vehicle, the P2325 code represents an issue that will have a definite impact on drivability. For this reason, it should be treated seriously.

What repairs can fix the P2325 code?

The following repairs may be necessary to clear the P2325 code:

Additional comments for consideration regarding the P2325 code

It is absolutely vital that the vehicle be inspected with an extreme attention to detail when it shows a P2325 code. Rushing through the diagnosis process could lead a mechanic to believe that the ignition coils or spark plugs are solely responsible. Addressing only that issue will not make the vehicle any safer.
