Default Re: toyota echo 2001 check engine light
Hey Mustang,

The overnight cooling down process did not work. So, I thought I would take it to the Toyota dealership to have them look at it. The person I dealt with there was kind enough to explain why, how and what these lights mean and glow. It was consistent with the stuff I have read on this forum. He brought out a small meter and plugged it in to the socket just beneath the dashboard where we have the lever that pops the hood open. He cleared the error and said that if it was the gas cap, then this should fix it and the light shouldn't glow again. However, if its some other leakage or other error, then it would come back up after driving 10-15 miles. So, far it hasn't come up again and I've driven about 30 miles or so since that.

The guy was nice and didn't charge a penny either for it.

Thank you again Mustang.

If a gas cap is left loose and then tightened (like you did), it takes either approx 40 ignition "ON/OFF" cycles to reset this "IF" the ecu dtermines that the evaprative MONITORS pass their internal tests and that they "SET". This usually takes a cooling down proccess of over 8hrs (usually overnight works) to set the monitors. There are also specific dive patterns that have to be met.
Having stated all the mumbo jumbo, I recommend clearing the engine light. If the light comes back on, then have the code READ and either take it to the DEALER or post the code here, then we can advise from there. There are over 300+ reason for the check engine light to come on... the code points us in the correct direction.
I recommend the dealership because, I have a hard enough time keeping up with ALL TOYOTAS, how can the people at independant shops (Firestone/pep boys ect....) keep up with ALL VEhicles. They are working at those places and not the dealer for a reason. Yes, I am biased, but I have seen and experienced those places and how far off MOST of them lead people.
Let us know
Thanks
