    I just want to replace them all considering I am a little over 250,000 miles. Can someone point me in the right direction as to which ones are which? There are 4 on the right side of the engine and just the imap on the left side. I am unsure about the right side.
    In the picture:
    1- exhaust pressure sensor (?)
    2- delta pressure sensor
    3- egr temp sensor (?)
    4- ? Temp sensor?

    It is a cm2350 built June 2015. If anyone has info or part numbers that would be awesome.

    So would #1 be intake pressure sensor?
    I think #3 must be intake temp sensor then ?

    The IMAP(intake pressure/temperature) sensor is usually on the driver side on the actual intake manifold.

    They're calling #1 the EGR Orifice pressure sensor. I'm getting all this from cummins quickserv(Cummins QuickServe Online | COLA) free to register upto 5 different engine serial numbers.
     
    gokiddogo and Jazz1 Thank this.
