Right on the top of the engine.
Right side of throttle body
IAT stands for the Intake Air temperature sensor. It is usually located in the air filter box or on the snorkle going to the throttle body
on a 5.3L it is behind the starter that must be removed first
Knock sensor for the GMC Yukon is beneth the intake manifold mounted to the cam cover.
Under the distributor cap.
It is located behind the intake on top of the engine. It is not the same thing as a Crankshaft Position sensor. Don't get the 2 confused. The Crankshaft position sensor is located behind the starter on the housing for the torque converter. The camshaft position sensor is harder to get at which is why many mechanics will try everything else before they check this sensor. In some cases the engine may have to be removed, especially if a unskilled mechanic tries to remove it and breaks it off. Make sure to use extreme care when removing it.
I have been having problems with finding the crankshaft sensor, what should i do or what can i do?
front of engine, behind the harmonic balancer
yes, under the rotor in the distributor
open your owner manual and you will find the answer.
As you look at the engine from the front, you can see the alternator on the right side. Just to the left of the alternator on the side of the throttle body, is the Throttle Position Sensor (TPS) - it is the top one - and the Idle Air Controller (IAC) - it is the bottom one. The TPS sticks into the side of the throttle body whereas the connector for the IAC sticks out towards the front of the engine.
