This has been happening to my car as well. It typically happens when your oxygen sensors start to wear out. Mine does it once in a while and I have the local auto store reset it. Go to your nearest auto store and have them tell you what code it is and ask them to reset the OBD so the light goes out. If the light comes on right away and the code has to do with your oxygen sensors, have them replaced. There are three, two are easy to replace, one takes some effort as it is in a tough to get to spot. The dealer will charge you a fortune to replace them so do it yourself or through a local mechanic. It is a very simple task other then the access.

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.

How to fix whatever caused the codes P0441, P0442,P0446


Check and make sure your gas cap is screwed on tightly. Then, check the vacuum lines are attached correctly and not leaking. I would bet one of the hoses came off or you have a hole in one or more. The hoses split with age. Start with these, before changing sensors or solenoids.

It was the bad ECU. I have the same 2003 ES300. I had the same 3 codes and after 5 months and figured out it was the bad ECU causing the error codes. Finally replaced the ECU and no more codes now

Had OBD2 codes P0441 & P0446 on my 1999 Toyota Corolla. Replaced the VSV CHARCOAL EVAPORATORE, disconnected the battery, check engine light went out. came back on this am, took the car to advanced auto...


According to my 2002 Toyota Tundra manual (and it may be different for your car) P0125 is as follows:
Insufficient Coolant Temperature
for Closed Loop Fuel Control

This would seem unrelated to your original problem.

My check engine trac off light came on


This happened to me as well, just a few weeks after buying our 1999 ES300. Took it into Lexus for regular maintenance and to check this out. Apparently, if you don't replace the gas cap correctly and tight enough this can cause the 'trac off' light to come one. It will go off a little while after the cap has been replaced correctly. This also happened with my 2006 Murano, 'check engine soon' message.

HAVE A CODE PO446 1999 LEXUS GS300 CHECK GAS CAP AND IT WAS OK. WHAT DO I LOOK FOR NEXT AND LOCATION OF IT


P0446 is an evap code. Most likely, you need to change the charcoal canister vent valve (CCV) under the trunk floor. Fuel cap codes set 3 codes at once, P0440. P0441 and P0446, all at the same time.
