    Hi new here have a quick question I have a Pete that's throwing all my sensors codes the truck doesn't shut down but the check engine light is always on. It has a 2000 n-14 celect plus engine. I hooked up the computer and I think the sid 232 supply voltage is the code that is cause all these problems with the other sensors. What I'm wondering is where do I start do I change each sensor one by one? Is there some test? Or maybe bad ECU

    That is low voltage at the sensor supply. It could be as serious as an ECM ir just as simple as a failed sensor. The troubleshooting for that code is not really hard, but you have a lot to check. What that codes means is high current at the sensor supply circuit. So it could be a sensor or a wiring problem. Unplug each pressure sensor one at a time. If 1 makes that code go inactive, that's the problem circuit.

    Go to https://quickserve.cummins.com/info/index.html and sign up. You get 5 free engines. Log in, put in your ESN and get the trouble shooting info. Or if you have Cummins Insite, the troubleshooting is in the help file.

    Thank you grape ape!!! I didn't the pressure sensor thing already none of the sensors cause the code to go inactive so imma change the wiring harness someone told me n-14 are notorious for this and it's usually wiring. So I'll try the wiring then see if I have an extra ECM close to this engines specs again thanks!!!
