Ok guys, this gets more interesting. My CEL Light came on again so please bear with me as I explain what is going on.. I have a 01 Camry 2.2L 4 cyl. I live in Texas and it has CALIFORNIA emissions! Imagine that!
When I got mine decoded the first time, it came up with several....
P0171 System Too Lean, Bank 1 P0420 Catalyst System Efficiency Below Threshold P0440 Evap Control System P1130 Air-Fuel Sensor Circuit Range/Performance
I replaced the Air Fuel/Ratio Sensor and cleared the codes. I drove around for about a month, and this morning the CEL Light came on again. When I got it decoded this is what I got
P0441 P0446
Now, I understand that these are in relation to evap leaks. Could it be my gas cap again? My Toyota buddy looked at my car this morning, and he was able to touch my catalytic converter. The car had been running about 20 minutes at the time, and I KNOW YOU CAN'T touch a cat if it is operating properly as they get extremely hot.
Now, he is telling me that I need to go ahead and replace my cat, which I am going to do, but what is weird is that it is not showing the P0420 code that the cat is operationg below threshold. Could a bad cat cause these P0441 and P0446 codes? He did tell me that one of the codes (I can't remember which one) is related to my evap canister. Can anyone tell me where this is located? Can you clean them and replace them?
I know this buddy really well, and I know he would not steer me wrong when it comes to the cat. He isn't even going to charge me to put it on. (Its nice to have friends like that )
So, any suggestions?
Thanks a bunch for any help! I apologize if this has been answered before!
