DTC codes / Toyota codes / P1310
P1310 on a Toyota means the engine control module (ECM) has detected a fault in the ignition circuit for cylinder number 3, specifically the igniter or coil circuit that triggers the spark. The ECM monitors the feedback from the ignition coil and sees an unexpected voltage or current condition that prevents it from confirming a proper spark event.
Guidance is general and written for Toyota vehicles. Exact tests and values vary by model, so confirm the fault before replacing parts.
