P1310 - FAULT CODE - OBD2

P1310 GM: IGNITION COIL 3 PRIMARY FEEDBACK CIRCUIT

P1310 TOYOTA: IGNITER CIRCUIT MALFUNCTION NO. 3

P1310 BUICK, CADILLAC: IGNITION COIL 3 PRIMARY FEEDBACK CIRCUIT

P1310 CHEVROLET: IGNITION COIL 3 PRIMARY FEEDBACK CIRCUIT

P1310 HYUNDAI: INJECTION CONTROL CIRCUIT FAULT

The DIS (Direct Ignition) system has eliminated the rotary distributors that deliver the spark that ignites the cylinders. Instead, these systems use signals provided by the Camshaft Position Sensor (CMP) and Crankshaft Position Sensor (CKP) so that the Powertrain Control Module can determine the most appropriate ignition timing based on the engine load and speed. The igniter allows performing greater precision when starting the engine, as well as decreasing the loss of high voltage that greatly affects the life of these components.

The igniter provides a primary ignition signal to the cylinders that are connected to the coil. The PCM determines when this signal will be delivered. Once it is received by the igniter, it is sent to the primary winding of the coil for the appropriate cylinder. After this process, the igniter power transistors interrupt the signal so that a high voltage is created in the secondary winding of the coil.

When the P1310 OBD2 fault code is set, it is because the PCM has found that the ignition system has experienced a malfunction. This is because an ignition feedback signal (IGF) between the PCM and the igniter or Ignition Module is not present. Number 3 mentioned in this code refers to the ignition circuit on cylinder 3.

• The Check Engine light turns on.
• The engine may not start.
• Reduced fuel efficiency.
• Lower engine power.
• The engine stops unexpectedly at idle
• Other misfire-related trouble codes are set.

Reasons for storing the P1310 OBDII diagnostic code :

• A circuit may have damage to wires or connectors.
• An ignition coil is possibly in bad condition.
• The cigarette lighter may be faulty.

Steps to troubleshoot the P1310 OBDII DT:

• Consult the Technical Service Bulletins (TSB).
• While the engine is idling, check that the spark plugs, coils, and wires for these components are working properly. Check the electrical connections for damage or improper fit. Repair or replace if necessary.
• Locate the manufacturer's source of information to access wiring diagrams and connector tables. Determine which IGT and IGF circuits are for the faulty cylinder, and verify that this circuit is not shorted or open. Also, check for proper resistance and continuity values. Make the necessary repairs.
• Check that the ground voltages are within the manufacturer's parameters with the igniter on. If these voltages are not adequate, replace the igniter.
