I went to VIP yesterday to get its serpentine belt replaced and its check engine light diagnosed.
The three codes that came back were: PO 120: Throttle / Pedal Position switch A circuit PO 441: Evap Purge Flow PO 446: Evap Vent Control
According to the VIP employee, I will probably just fail inspection. Of course, fumes could start leaking into the compartment. I have not smelled anything yet. Then again, it could be carbon monoxide. I also drove the car 400 miles round trip from Maine to Vermont two weeks ago. I have the luxury of walking to work during the week.
I am interested in being pointed to a resource on the codes, perspectives on them, or any other opinions on them. The three alternatives that come to mind (I'm sure there are more) are:
1) Ignore the light. Do nothing until the car stops working. This is probably unwise, but worked for 2-3 weeks and is still working.2) Buy a diagnostic tool (I've heard these range from $50-$200) and monitor the codes on a weekly basis. If nothing changes, then I am compelled to do nothing.
3) Take it to a Toyota dealer as the VIP employee recommended, have them find the leak and fix it. My main concern is, what is the estimated cost of fixing those problems?I welcome all feedback appreciatively.
