CEL came on randomly

hey just wondering if anyone knew about codes PO446 and PO773. My car was fine this morning, went to school, then started my car after school and the CEL came on. I took it to autozone and got those codes. Any help or suggestions?

thanks, so do you guys know if P0446 (Evaporative Emission Control System Vent Control Circuit Malfunction) and P0773 (Shift Solenoid "E" Electrical) are serious issues?

well did you clear the codes ?? If no . do it remove your battery terminal. drive around and see if it comes back ..

The shift solenoid "E" is the solenoid that locks the torque converter at cruising speeds, in most cases solenoids are not the problem, they get clogged with foreign material and stop passing fluid or get stuck, I would recommend removing the transmission oil pan and inspect it for any metal particles in the bottom of the pan and if there are, the transmission is the problem and it will need to be replaced.

yikes, i hope i would not have to replace my transmission, that would be a nasty problem. I guess im gonna go ahead and check these issues out tomoro

and thanks ruskimafia and midias for you guys help!!

When I had p0446 it only came on in the summer so I had my car inspected in the winter.

my 97 camry 2.2L has the P0773 code, along with P1133, P1135.
one is a transmission solenoid E electrical code,
one is a Air/Fuel Ratio sensor code,
i've tried to drain and refill ATF 4 or 5 times, the transmission still seem to shift a little bit rough, then until i replaced the A/F sensor, reset codes, nothing coming back now, i think the A/F sensor malfunctioned, engine lost power, and shifting late, causing the P0773.

hard to believe, but a new A/F sensor fix my P0773 error.

i would just reset the code, see if it will come back.
