what are the 3 sensors that are on the intake?

 

you mean on the throttle body? they are Idle Air Control, Throttle Position Sensor, and the MAP Sensor. the order i wrote them are gong from back to front. Map will be the sensor your staring right at in the front if ur in front of ur truck lookin at the engine.

 

Seems like a kind of vague question. If it is actually the intake itself, there is the IAT = intake air temp sensor, and possibly 2 coolant temp sensors(one for the gauge and one for the PCM). Need a little more info.

 

Not the sensors on the throttle body. The 3 sensors on front of the intake itself next to the thermostat and on the left front top of the intake.

 

top front passenger side up high is IAT.

the one or two front low, near the t-stat are coolant temp sensors. some years have one, some have two.

 

^ correct

 

Yea, kind of like what I already stated right?
