Check Engine/Traction Control Light SOLVED!
Just wanted to post that my 2010 Toyota
Camry had its check engine light AND
traction control light come on at the same
time. My car wouldn't shift correctly and
made a humming sound when driving right
after these lights came on. Anyway, we
recently had the car serviced and the air
filter cover was not put back on properly.
Once it was, the problem was gone and the
lights shut off!
