Default ISM Sensors

I would like to gather spare sensors for my ISM 11 Cummins. Anyone have suggestions on witch ones are prone to failure? Mike McGraugh is the only one I know of that replaced any. Are there others?

Rick, Replaced the cam sensor on my M11 and it appears to have solved an intermittent no start problem. These are known to crack and fail. Found mine on Amazon. Cummins #4326596.
Nice if we could get part numbers for all the sensors on one post.

i was told that engine position sensor and boost pressure sensors can go bad and not show a code so to change them as preventive maintenance every 5-7 years
( this time frame is for guys like us with motor coaches with m11's- not simi's)
by a man that sells parts to servile road mechanics and does cummins computer programing,,when i pulled my engine position sensor it was indeed cracked...

According to Cummins, the Cam sensor (No crank sensor in ISM) has 2 sensors in it. If the first one fails, it sets a code and reverts to the second sensor and keeps running!
Both sensors are in the same thingy! That's why it has 4 wires.
If you know where the cam is, you better know where the crank is!
They are only $40 from Cummins with the Power Club discount so why not?

Kind of a pain to get to as it's behind the Compressor
