When you have P0440, P0441 and P0446, it is a very good bet that the fuel cap was loose, or the fuel cap rubber seal is compromised. You will get all three of those codes every time that the cap is loose. Always make sure that the fuel cap is as tight as you can get it after you refuel.
I have a 2000 lexus rx 300 I have replaced the evap canister. Then I had a code 0440 pop up and a code that said fule mixer sensor code pop up I had this replaced. Now the evap canister malfunction code is back 0440 and no other code what is the problem?
On this make the warning lights all come on together, the check engine light is the cause of all.
Hello
When the service engine
soon light (Also called the check engine light or engine management
light) is turned on this is to alert you to the fact that Powertrain
Control Module (computer) has detected a failure somewhere in the
systems it controls you may not feel any difference in the way the
engine runs, this can be the transmission or the engine or emission
system, there are fault codes set in the modules memory for these
faults. What needs to happen now is to have the powertrain control
module scanned with a special tool called an OBD2 electronic engine
control scanner or a OBD2 code reader. Once the code(s) are read then
you must perform the diagnostics for each code and make the
appropriate repairs based on the findings of the diagnosis that was
performed, this is called doing "Pinpoint" testing.

LS430 year 2001, check engine light started to come on then off for a while then on again. After connecting a scanner to read the code, Check VSC control message showed up. 104000 miles, just ordered new spark plugs for it. Could this be emission related caused by old spark plugs? If not, then what?
Thank you.
