Engine Code

[Lakerboy909]

Anybody have familiarity with this code?

Engine:128
SA:0
SPN:105
FMI:2

Charge air intake sensor is what I'm getting. Am I reading it wrong? Thanks everybody.

SPN 105 is the intake manifold temperature sensor, you didn't mention what year your truck is. The earlier engines used 2 sensors one for pressure the other for temperature, the sensor is capable of doing both so newer engines only had 1 sensor. Regardless the temperature sensor is located in the back of the intake manifold. If you have a older engine with 2 sensors switch them and see if the fault goes away.

Also if you have the under hood inlet air flap valve check that its not stuck open!

I have a 2012. Thank you sir for answering. I've had this truck for a year now, it's been a good truck for me. Where can I find aftermarket stuff for macks? For example, exhuast manifold, exhaust systems etc.... Dynaflex said the freightliner kit might fit on the mack, and I can't really find anything with bully dog or anybody.
