Why is my Check Engine Light on?

Click Here to see the video! Owning a car is a big accomplishment, but it comes with many responsibilities. Car trouble cannot be avoided, but experts like Dean Bailey can be a big help. Take for example some cases that Dean Bailey has been able to help with. Pam from Wake County has a 2003 Toyota Camry. Its “check engine light” has been turning on and she has been told it could be her catalytic convertor. Wanting to fix this problem, she asks Dean Bailey for choices on how to continue with this matter. Dean Bailey believes that she does need to get her car checked further because it could be the oxygen sensors. There is not an inexpensive fix, if the catalytic convertor is the problem and needs to be replaced. There are chemicals that can be used but they are not very effective because it builds up a lot of residue internally. Ted from Wake County has a 2004 Hyundai Sante Fe that hesitates when he backs up and puts his car in drive. He has had the transmission fluid flushed and filled. Dean Bailey believes it could be a solenoid; most transmissions now are controlled by a computer, and at times the solenoids would stick or bind up internally and they usually need to be replaced to fix it and a scan can see if it needs fixing. Oveda in Wake County has a 1995 Chevy Cavalier who has bulbs that keep going out, especially when she drives over a rough spot, even though the bulbs and housing have been replaced. Dean Bailey says that she should look at the sockets again and maybe get new sockets for the bulbs instead of taping them together. Pearl has a 2003 Honda Accord who hears a clicking when she switches from first to second gear. Dean Bailey believes it can be the constant velocity axels but it could also be the transmission and engine mounts as well. When shifting from first to second most of the load is on the car and that is when it is felt the most, but it may not be felt in third or fourth gear. Carol says her 1997 Chrysler Town & Country does not idle correctly all the time. She replaced the map sensor twice, the check engine light turns on periodically, and the computer diagnostic program did not show any problems. Dean Bailey says that at times the Exhaust Gas Recirculation (EGR) valve binds and stays open when it should be closing and this can cause a rough ideal and the check engine light to turn on.
