Camry 2003 LE
132000 miles

The check engine light has just turn on. I found the following fault codes set P0420, P0441, P0442, P0446. Could you please help me understand in order these codes should be fixed and how much would it cost to fix them.

Thanks,

 

All these codes refer to a problem with the cars fuel tank emissions system called EVAP.

The link below provides some info. It's for a Sienna but should be close enough.

How to fix your Toyota Evap P0446, P0442, P0440 Check Engine Code problem for less than a million dollars.

Lower priced after market parts are available if DIY. Cost around $250.

Any competent shop can repair the car, not just Toyota dealer. Parts and labor of course will be higher at a shop. Perhaps 1 hour labor plus parts.

Could also be fuel cap, take note in article about the lack of noise when opening cap due to leak.
