The P124C fault code refers to a problem with the injector 5 positive voltage control circuit being shorted to the control circuit. The Engine Control Module (ECM) supplies voltage to each fuel injector, and when a circuit condition is detected, the affected fuel injector is disabled. In this case, the ECM has detected that the injector 5 high control circuit is shorted to the low control circuit for more than 2 seconds, triggering the fault code.

This means that the fuel injector 5 is not receiving the proper voltage control, which can lead to issues with fuel delivery and engine performance. It is important to address this issue promptly to ensure optimal functioning of the vehicle.

What are the possible causes of the automobile fault code P124C?

If you see the engine light or service engine soon warning light on, the fault code P124C could be the culprit. This code is often caused by a faulty fuel injector 5, an open or shorted fuel injector 5 harness, a poor electrical connection in the fuel injector 5 circuit, or a faulty engine control module (ECM). To fix this 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 P124C fault code?

If you’re dealing with the P124C fault code and your engine light is on, it’s time to take action. The culprit could be a faulty fuel injector 5, an open or shorted fuel injector 5 harness, a poor electrical connection in the fuel injector 5 circuit, or even a faulty engine control module (ECM). To fix this issue, start by visually inspecting the wiring harness and connectors. Look for any signs of damage, such as broken, bent, pushed out, or corroded pins. Don’t delay – check these possible causes and get your engine back in top shape.

What should I look for when checking for damaged components and connector pins to resolve the P124C fault code?

When resolving the P124C fault code, start by checking for damaged components and connector pins. Visually inspect the wiring harness and connectors for any signs of damage. Look for broken, bent, pushed out, or corroded pins on the connectors. This can help identify any issues with the fuel injector 5 or its circuit. Don’t forget to also consider other possible causes such as a faulty fuel injector or engine control module.
