Description of DTC code P1300

In engines with the Direct Ignition System (DIS), manufacturers do not use rotary distributors that deliver the ignition spark to the cylinders. Instead, they use the signals from engine sensors such as the CKP Sensor (Crankshaft Position Sensor) and the CMP Sensor (Camshaft Position Sensor). These sensors allow the Powertrain Control Module (PCM) to determine the optimum ignition timing for engine speed and load.

The fault code P1300 OBDII is a manufacturer specific code, which refers to a malfunction between the igniter, (also known as ignition module) and the PCM. This failure is due to a lack of ignition feedback signal between the two components. In some applications, the igniter may delay or advance the ignition time, while in others the PCM takes over this function.

Symptoms of fault code P1300

  • Check Engine lamp illumination.
  • The engine may not start.
  • Reduction of the fuel office.
  • The engine loses power.
  • Unexpected engine stop during idling.

Causes of OBD2 P1300

The reasons for setting the diagnostic code P1300 OBD2 are

  • The lighter may have damage to its cables or connectors.
  • The ignition coil may be in bad condition.
  • The lighter may be defective.

Possible solutions of the DTC code P1300

To solve the DTC code P1300 OBDII, you must take into account the following:

  • As a first step, you should consult the TSB (Technical Service Bulletins).
  • Check all the components of the ignition system. Check the condition of the cables and connectors leading to the ignition coil, as well as the spark plugs. If the damage is found, make the necessary repairs or changes.
  • Consult the service manual to locate the components associated with this code. Identify the IGT (Ignition Trigger) and IGF (Ignition Feedback) circuits for the affected cylinder. Check for open or short circuits between the coil connector and the PCM Repair as necessary.
  • To perform the most advanced diagnostic steps, consult the vehicle's information source. If you determine the igniter is defective, you should replace it.
