Good evening everyone code 125 isx15
Hey everyone I just started getting code 125 today on my 2014 isx15. Im stuck over here in Brunswick ga about to try to make it to kw savannah in the morning . The problem I am having it runs fine then dies . I hook up insite and get code 0125intake manifold 1 pressure sensor. With this being bad cause code 0755 as well. Everything is new on the fuel side, new pump, plungers , backflow valve etc. It just started it at 1 pm today. What are the symptoms . I was giving it fuel backing in and it died had to hook up insite clear the codes. Im still learning this but got my wrenches . Thanks a bunch

That could be the problem right there!! Don't bother to clean it, just replace it.

That 755 is a fuel rail pressure code. Could be the fuel rail pressure sensor. Have you run a rail leakdown test on it with insite lately?

don't forget to check the wiring harness(es) connected to those sensors and the grounds. you can use insite to monitor the sensors and voltages too. not saying it's the problem, but something to consider during torubleshooting.

I bought the new sensor and seems to have cleared it up but the old one was full of soot.

Pure neglect.

That means the rest of the engine's EGR circuitry needs cleaning out too. That is exactly wnat causes repeating DPF problems.
