2013 ISX 15 Fault Code 3165

[Rawze]

Sounds to me like you may have been driving it against a check engine light already? ... red stop light for emissions does not usually come on with that fault unless you were ignoring other problems for a while.

* When is the last time you did a thorough EGR-Tune-Up, inspected things, etc?. I know you have mentioned it in the past.

* have you taken an el-cheapo temp gun at any point and verified the temp reading(s) that are shown in Insite?

* When is the last time you inspected the face of the SCR element?. This can cause high SCR outlet temps too. Just recently had someone over for just this problem: http://rawze.com/forums/showthread.php?t...5#pid42685

* What do you expect the stealershit to do besides rape you for all you are worth, tell you that you need new turbo, new DPF, new SCR can, and about 10 other really expensive tings? then send you down the road a few hundred miles a few thousand $$$ raped dollars later,.. only for it to do it again?

* What steps have you been taking to prevent such problems to begin with in the last few months?

* When is the last time you replaced the air cleaner element? - The crank case filter?, had the CAC and engine pressure tested?

* How many Miles, and some more history of the truck, operation, etc. would help too.


============

higher than normal exhaust temps can usually be from ...
* dirty CAC unit.
* Clogged air filter, or clogged up crank case filter (throwing the combustion off).
* Mis-reading IMAP or other EGR sensors.
* inefficiency/restriction in the EGR cooler (old/sooted up badly).
* an egr circuit leak.
* an exhaust leak (during regen cycles).
* mis-reading egr sensors or stuck egr valve.

* clogged up exhaust piping (ref: http://rawze.com/forums/showthread.php?t...07#pid1807 )

kinda points in the direction towards these types of things anyways.

Remember .. those cans are all passive. It is engine problems, or clogging due to engine problems that make then not run right.
