Fault Code 1141

[Rawze]

- Start by replacing the exhaust gas pressure sensor. Be sure to use OEM only for it, as those dorman brand and other knock-offs are notorious for giving false mis-fire detections.

- Also do an injector leak-down test on the fuel rail. It should be done just like this video shows at 29,000 psi and not just at idle psi.

- If it leaks down more than 4,000 psi in 60 seconds, then solve whatever is causing that issue first.


After that, if it is still reporting injector #2, then its likely is going bad.

=========

- If the truck is de-mandated (has delete programming) then you also need to have that checked out/reviewed too... to ensure it is not causing progressive engine damage over time. More than 90%+ of all delete programming is absolutely harmful and can cause premature injector failures, turbo issues, ghost problems, and even head gasket issues, or worse.
