Title: Temp sensors question
Post by: SuperPete on October 25, 2019, 02:36:09 PM
Hello, question about temp sensors,

So from what I understand correctly:
INTAKE TEMP (IAT)- is your temp sensor right at the airfilter.
IAT2 IN DEGF - is it at the throttle body or at the its 3BAR Map one?
CAC TEMP - Again, I am confused what sensor is this? Throttle body or MAP


Please shine the light on this,
Thank you

Thanks Z,
So

INTAKE TEMP is at Airfilter temprature
IAT2 is MAP Seonsore temp

What is CAC TEMP then?
Anyone?

CAC is charge air cooler (intercooler).  It is the temp of the air exiting the intercooler.

Ok, there is no temp sensor between intercoller and TIP sensor, so I guess its TIP sensor reading then, agreed?

The Front Pre-throttle body TIP/MAP sensor is for your (CAC) Intercooler!
For example if you accidentally installed a 2-bar map sensor in place of that 3-bar map sensor your vehicle will run like crap similar to being in limp mode based on Speed Density.

There is also a (CHT) Cylinder head Temp sensor conjunction with the (IAT) Sensor. Z

10-4 Z!

Now, I been watching temps for few days,
see picture attached as example,

65F Outside, driving around town highway speeds,

69F at Intake, thats good
78F at Throttle body, not bad, GH Intercooler doing good job
104F in Manifold, Thats little high and normally it stays 105-115 there,
I understand its bolted to engine and taking up all the head from the engine block, and even wrapping it probably not going to change that, I am correct in my observations?
You guys seeing same numbers?

Thank you
