the 2.0L engine has this. and one more hidden inside the MAF

see, it there, it's real name is IAT and they never go bad.
Im not arguing name , but is very important go use them.
The IAT is the USA /ASE/SAE name. (and function for EFI controls.)
so why not post symptoms or state the job.
so we can be on same page.?
are you hacking it? (you will fail, if you do , i promise)
to change it, unplug it. then remove it
reverse above, same with all sensors really
but all connectors are locked, and all FSM on all cars
tell you how to do, (press lock and gently pull)
think this IAT just pulls out. of a rubber grommet.
in some countries, (you never said) the car
has no
IAT at all. so...... can help much ,.
my 92 vitara has non then was added in 1993. on up.
in USA.
in some countries other parts are missing to in the EFI system
and uses different spark system.
mine uses COPS others use a single twin coil pack
my point,, no country ,no joy,
