cant find much info about it. its one of the last sensors i havnt replaced. cant seem to find a new one either.

how do i test my one?

what are symptoms of a bad sensor?

i havnt touched the housing for it either, seems to vent two things into my intake, im guessing charcoal cansiter and oil breather?

stil feels like my cars not quite idling right, from cold it hesitates/stutters at bang on 2000rpm for the first minute or so.
after that its fine, pulls ok, but still feels a little lumpy at times.

between this sensor and the charcaol cansiter system messing up somthing im not sure what else anymore.

quite unlikely in the ambient temperatures we see here, you mean the yellow plug on the front not the grey one right?

bump:

my idle problem was the green temp sensor.....

but back to the yellow throttle body heater

looking at the wiring diagram.....this thing is on non stop if you are driving. (p**sing useless heat into the manifold)

i have removed the yellow heater for testing today.

on my bench power supply it initially drew over 1.6amps dropping to about 0.6amps once it was up to temp. i figure attached to the throttle body it would take a fair bit longer to get upto temp.

after discovering all this....it has been removed permenantly with no ill effect.
