Thank you for choosing JustAnswer and allowing me to help you resolve your Toyota questions!
At any time during driving while the check engine light was on did it start to flash at all? Do you have a code reader or no what the malfunction code number is XXXXX may be set in the engine control computer causing the check engine light come on? Are you noticing any loss of performance or acceleration?
It hasn't flashed at all. There is no loss of performance or acceleration. I don't have a code reader, but I can take it to various shops; but I don't know who's reliable and honest. So, I don't know any code. The engine doesn't seem hot-- the dial seems to be in the "normal" range.
