The P1277 fault code refers to a specific issue with the Injector Driver Module (IDM) in an automobile.

The IDM has the ability to detect if individual injectors are open or experiencing shorts to either ground or power while the engine is running. It can also detect if there are high side circuit opens or shorts to ground on either the right or left bank.

In the case of the P1277 code, it indicates a low side-to-high side open in the circuit between the Injector Driver Module and cylinder number 7. This fault code helps identify and diagnose the problem, allowing for a targeted fix to be implemented.

What are the possible causes of the automobile fault code P1277?

If you see the engine light or service engine soon warning light on, the fault code P1277 could be the culprit. This code is often caused by a faulty fuel injector, a faulty injector driver module (IDM), an open or shorted fuel injector harness, or a poor electrical connection in the fuel injector circuit. 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. Don’t forget to check the possible causes mentioned above.

How can I visually inspect the wiring harness and connectors to fix the P1277 fault code?

If you’re dealing with the P1277 fault code and your engine light is on, it’s time to take action. The culprit could be a faulty fuel injector or injector driver module, an open or shorted fuel injector harness, or a poor electrical connection in the fuel injector circuit.
