Hello, My name is Steve and I may be able to help you out. There should be an FMI number with that SPN number can you give me that and also the engine serial number so that I can figure out which fuel system the engine has so I can give you the proper information about the fault code.


FMI 14 ENGINE NO 37238317


Good morning, It looks like the fault code that you have refers to an OEM oil pressure sensor that is out of parameter, this is not the engine oil pressure sensor but a sensor for a pump drive, transmission, etc. that the engine is monitoring and protecting. Here is the diagnostic information for that circuit. Please let me know if you need any further help, Thanks, Steve Phillips
