Does anyone have a part number for the intake manifold pressure sensor on a Cummins 8.3 ISC? My warning light is on, and I am getting code 123. I just corrected all of the other fault codes, and this is the last one. I just can't find the part number?

Thanks!

Hi Krash; Kind of a late response as maybe you already have an answer to your question. Did you by any chance sign up to be a Cummins' Quick Service member. Once you set up an account and put in your engine serial number, you can look up all sorts of parts for your engine. The site also has engine fault codes That's how I found the old part number for my Barometric/Air Pressure Sensor for my 01 ISC. I also had great luck talking to Cummins's support over the phone. That number is listed at their web site. Their level 2 tech's saved me hundreds of $$ by working out a location of a part replacement for me. Good luck!

Hi again Krash; Just spent some time on the Quick serve site. For my 01 ISC for the intake manifold pressure sensor, it shows Part#3348747. Went to Bing and found numerous listings for that part#. Also some other part numbers that could be for that same part. Also under active fault codes, it shows a problem with the part in question. Hope this info helps!

Thanks Oilburner. I seem to have problems using Quick serve. It lets me log in and displays my engine number, but it only lets me look at a few things. I am sure I am doing something wrong.

I bought the part from Cummins for $88, and the part number was on the box. It is 4921497. Then I found it at other places for $17-24.

It is already in place, and my codes are clear.

Good going Krash; It takes a while to lean how to navigate the site. Trust me. You kind of have to start clicking on descriptions for areas like wiring diagrams etc. It will take a while but you will get there. Glad you got her fixed. Also, I bought my Barometric/air pressure sensor from my local Cummin's for $87 + tax. Then a friend with a Monaco coach sent me a site that had it for $57. Can't win when you need it know. Have a great evening!
