I had the 105K mile service (plugs, belts, drive belt, oil change, etc..) performed on my 00 TL about a month ago and all of sudden, nothing seems wrong with the way it runs or anything, but CEL comes on and TCS light....

Took it to Autozone to check, they pulled P1519, 170, 171 out of the computer...

Any ideas?!?! I did a search couldn't find anything helpful on these codes...

please help

This is a pretty extensive list. Should tell you what the error codes means. I cant help you out more than that though since i dont know how to fix them.

Do you have any idle fluctuations?

OrionHCCA

The idle does fluctuate a little. When I start from cold now, it maintains at about 1200, when it used to be 800ish... even after I shift out of park... I did read a little something that it could be related to the IAC valve...

Where is the IAC located on the car and do you know anyone with a how-to? if that;s what you think it is?


thanx

sbuswell

sounds like you need a new IAC valve and maybe a new O2 sensor.

I just repalaced the IAC about 2 months ago with a brand new one from the dealer. very easy change.. now that I remember... I must have had a major brain fart yesterday...
