I see the code popped up.
where is the coolant temp sensor located?
and anyone know the part # for 99 2.8?

[A62TURBO]

Its under the coolant expansion tank.

[oc-drop]

on the 2.8 its sort of under the MAF near the throttle body

if you look under the MAF near the back of the engine you should see a blue/green top fastened in place at the end of a metal tube

change it before you get stranded, dont forget a new oring


btw purems.com sells it for less than $20 iirc

[audihtp]

OC-Drop,
thanks man didn't know there is the right instruction with right pic.
so I got the o-ring and sensor. even though my CEL went away but replacing it anyway since it's got
about hit 150K miles. and looks like gonna have to do it tomorrow.

next I guess to have trans oil/filter change and have independent place check the axle etc.

I forgot to say you might need a new clip for it as well =)

always good to change before it goes completely bad... it stranded me on the way home once... it was a whole weekend ordeal that sucked!

[audihtp]

yeah shouldn't be that hard to remove the clip without breaking it. my hands are small enough to fit that space without removing duct I tried but engine was hot... but able to to pu my hand in there.

well just update, I was able to take the clip from harness and take connectors out. but had to stp it was still hot!

so will see how it goes tomorrow.....

yeah went to get new clip this morning. dealer right by my office.
so hope rain stops in the afternoon.

[audihtp]

I was able to do it but man it was tight squeeze to put both my hands in there and trying to put clip back on.......
but man what a difference with new sensor... I guess it was bad to begin with, it's running much better than before...
thanks for the info to OC-drop.
