P2310: Ignition Coil D Primary Control Circuit High
Do not keep driving
Stop if the engine light is flashing. Note whether the fault appears only when warm, and ask for the connector to be checked before the coil is replaced.
What this code means
Coil D's primary control circuit reads above its valid range — an open circuit or an open primary winding. The reasoning is at P2301 and the heat pattern at P2309.

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
