    May be we use different quality fuel, but I usually see bad EGR

    Just had my truck into the KW dealer last month for a few things, including the PID 131 code.
    The exhaust pressure sensor was the culprit there. Little brass piece of crap about the size of my thumb that costs about $100.

    I probably will have it hooked up to the diagnostic computer soon as the engine warn and work light can only be turned off via computer any way ... One place charges $125 to hook it it up but will apply that to any labor needed to replace a sensor. I had a brake light I found was not plugged in so when I cleaned connection and plugged it back in the 2nd fault PID 131_P went away on it's own.
    Got a wiring diagram from cummins for 16 bucks and air plane wiring expert buddy will try to figure other stuff out soon...Thanks for input ?

    I also get pid 131 active code, exhaust gas pressure incorrect. Was gonna change the exhaust pressure sensor. Where is it exactly on a 2007 ISX. Took truck to KW dealer on this code and they changed the intake manifold sensor, the one on the top. But still have same code come up. Thanks
