CTS...where are you?

[madhat]

I am getting a code 15 and I've checked most of the things related to it...and I was wondering where the CTS(coolant temp sensor) was...I've got alot of the signs of a bad CTS, but dont know where it is...

its on the front edge of the right side of the intake as you are looking at i8t, drivers side. right near the alt bracket

To clear up some confusion. The CTS that the ECM monitors is the one on the driver's side of the upper radiator hose sticking out of the front of the intake manifold(two wires). NOT the one on the driver's side top of the coolant passage(one wire), NOT the one on the passenger side of the upper hose on the front(one wire).

Well, found it and got the rusted thing replaced! Had to take back the first one..woulld thread...second one is too long(autozone replacement not official GM) but it fits and works! Now, I just have to find that darn vac. leak!!
