2000 RX 300 CEL (update of previous thread)
Hi all, as my rx 300 had p0440, p0446 codes, we took it to the shop.
After all the talking and some more talking, the guy at the shop said he still need to do some more testing.
Just to sum up my problems with EVAP code(p0440, p0446, p0441), we started to have these codes back when we first purchased car in last december. (used with about 72,000 miles on)
and ever since then, we have changed gas cap, canister, a/f sensor and so on.
Yet, the guy at the shop tells me he wants to do some more testing.
He mentioned something about doing a smoke test to see if there is any leak through the hose.
Also, he said looking into vapor pressure sensor circuit could be another possibility.
This shop is not lexus nor toyota. It's just a small shop where the dealer whom we purchased car from have recommended us to go.
My question is:
1. How much would it run (estimate) to do a smoke test?
2. If there is any leak, then how much should we be expecting to dish out?
3. If there is a problem with vapor pressure sensor, then how much more would that be?
4. In the end, what would be the worst scenario we can have? (as I have mentioned, we had to dish out about $1000 already, including replacing canister)
5. Lastly, would it be better to just take my vehicle to toyota or lexus??
Honestly, I am not sure if these guys know what the real problem is.
If anyone could help me with these questions, that would help me and my
family a lot.
Thanks to all
Shawn

The person who can answer your question is the mechanic who is working on the car.
What is forcing you to go to this mechanic .. are you paying out of pocket? If so I would suggest that you need to go the Lexus dealership and provide them the history of the current repair work.
The problem right now is we can not tell for certain how long it will take this mechanic to fix the problem. At the same time, I cant tell for sure if the dealership will nail the problem at the first go.
If I were paying for the repairs out of my own pocket, I think it would be time to cut the bait and go fish.

I am with Salim on this on 100%. There is also no guarantee Lexus or Toyota would nail it either. However, both would have a lot more equipment to be able to check these systems to tackle the problem. In the end, they are really the last line of defense.
