how to clean sensors?

[Milky6]

How do you clean the throttle body, maf sensor, and coolant temperature sensor? I've searched these but i have not found an answer. Also, where is the coolant temp sensor?? There was a thread i read where this question was brought up, but never answered. Thanks for your time guys! :sadwavey:

follow the upper radiator hose, where it goes through the intake manifold is where you will find the coolant temp sensors

Get a Throttle Body brush and TB cleaner to scrub the TB and surrounding area clean. Don't use Carb cleaner cause it can fubar the IACV.

cool.. but how do i clean the coolant temperature sensor and maf sensor? do i just wipe it down with a cloth or something?? or do i have to use type of cleaner?

Buy a new CTS. Why do you want to clean the MAFS?

my idle bounces up and down. I've read in previous threads that cleaning the maf sensor can make it better or fix the problem. How much do cts's go for anyways?

Sure it's not the IACV that's gummed up? The CTS is $20 from Nissan.
