The P1305 fault code indicates a problem with the igniter circuit for cylinder number 2 in the Direct Ignition System (DIS).

This system is responsible for igniting each cylinder individually using one ignition coil per cylinder.

The igniter, which is integrated into the ignition coil, receives an ignition signal (IGT) from the Engine Control Module (ECM) to determine the timing of the ignition. In the case of the P1305 code, there is a malfunction in the igniter circuit for cylinder number 2.

This means that the power transistors in the igniter are not cutting off the current to the primary coil in the ignition coil as they should, resulting in a failure to fire the spark plug. The ECM detects this issue by monitoring the IGF circuit, which confirms whether the primary switching occurred properly. To resolve this fault code, the igniter circuit for cylinder number 2 needs to be inspected and repaired.

This may involve checking the wiring connections, testing the power transistors in the igniter, and ensuring that the ECM is functioning correctly. It is important to address this issue promptly to avoid potential engine misfires and further damage to the ignition system.

What are the possible causes of the automobile fault code P1305?

If you see the engine light on or the service engine soon warning light, the fault code P1305 could be the culprit. This code is often caused by a faulty ignition coil No. 2, an open or shorted harness, a poor electrical connection in the ignition coil circuit, or a faulty engine control module (ECM). To fix the issue, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the wiring harness and connectors to fix the P1305 fault code?

If you’re dealing with the P1305 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty Ignition Coil No. 2, an open or shorted harness, a poor electrical connection in the circuit, or even a faulty Engine Control Module (ECM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look out for any damaged components and check for broken, bent, pushed out, or corroded pins in the connectors. Don’t delay, get to the bottom of this problem and get your engine running smoothly again.

What should I look for when checking for damaged components or corroded connector pins to resolve the P1305 fault code?

To resolve the P1305 fault code, start by visually inspecting the wiring harness and connectors. Look for any damaged components and check for broken, bent, pushed out, or corroded connector pins. These issues can cause a poor electrical connection or an open or shorted circuit, leading to the faulty ignition coil or Engine Control Module. By checking and addressing these possible causes, you can fix the problem and turn off the Engine Light or Service Engine Soon Warning Light.
