3126 high intake temp derate

[Rawze]

Not sure about CAT but high intake temp readings are a sign of the turbo not being able to push air properly for most engines.

* blocked intake.
* Blocked exhaust.
* Excess soot damage to turbo because of excess engine soot, Usually looks like acid has etched the exhaust or VNT/VG blades on the turbo once taken apart.
* Carbonized turbo bearing from excessive heat and poor air flow, or someone shutting off engine a few times with turbo hot.
* Blockage in CAC.

All I can say is that engine abuse = engine problems. Yes they are likely related. - Jump over a dollar to save a dime trucking.
