P2310: Ignition Coil D Primary Control Circuit High

Standardized SAE J2012 code · P23xx — Ignition system and misfire

What does P2310 mean?

The ECU detects an excessive voltage on the primary control of ignition coil D, normally caused by a short to battery or an open primary winding.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Common causes

  • High Primary shorted to battery
  • Medium Open primary winding
  • Low Connector pins corroded - high contact resistance

Likelihood is a general estimate across vehicles; your make and model may differ.
