my 2003 RX has the VCS & check engine lights on. codes read PO441, PO442, and another PO (lost the 3rd sheet with the 3rd code, PO446??)
Is it OK to drive it for awhile as I foresee a heafty bill. I have replaced the gas cap and cleared the codes but the VSC stayed on and the check engine came back on today. The codes cam on 2 days after being inspected and passing emissions test?? took it back to place who did the inspection and they cleared the codes and did nothing else?? they said to bring it back if the codes came back on and the would have to smoke it to find the leak ?? I need some help!
Thanks

 

I would suggest this being moved to the RX forum so you can talk to RX owners who will be more helpful with this specific situation

 

Please read RX300 Mega thread Having problems Start here sticky thread.

Trace/diagnose based on the codes. Mechanic did the right thing by resetting them the first time.
