What does the engine code P2310 mean?

Definition: Ignition Coil ‘D’ Primary Control Circuit High

The engine code P2310 means there is an issue with one or more of your engine’s ignition coils. An

ignition coil

is used for induction in the engine, using the voltage from the battery to create an electric spark in the spark plugs and ignite your engine’s fuel.

In modern cars, ignition coils are controlled by your car’s computer. That means the issue can lie both with the coil itself, or how it is communicating with the computer.

How much will it cost to fix?

Diagnosis of the issue should take an hour, and cost between $75 and $150. If the coil needs to be replaced, the coil will cost between $60 and $80 and labor will cost between $100 to $200.
