How does a mechanic diagnose the P2324 code?

  • Clears code P2324 from the ECM and verifies whether the code comes back

  • Tests the coil primary internal circuit for continuity

  • Tests and checks the primary coil connector and wiring for continuity

Common mistakes when diagnosing the P2324 code

  • Clearing ECM memory codes before checking the freeze frame data of the failure
