01 v70 t5 P0172
 

I have a 01 v70 t5 with 130,000 on the car. Just had the maf go bad, replaced new. Then came front 02 sensor , replaced new. Now the error I get is p0172. I replaced the MAP but still have an the issue. Car runs fine until I put it in park, rpms drop and then come back to normal. If I run errands and start and stop the car through out the day it will not start until I clear the code. I have checked for vacuum leaks and do not see any. Any help would be great! Thanks

Whenever I had that code it was the PCV vacuum line at the TCP valve connection, the small one.

Thanks, I will take a look and see.

Hello, What does TCP stand for and where is it? thanks, Kira

Can't remember what is stands for, I'll look it up when I get back on my computer (I'm mobile right now). It's at the back end of the intake tube, down stream of the MAF.

My bad, it's called a PTC (had the p in the wrong place). Here is the link to it.
