Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello and welcome
There are a couple of things you can check yourself, make sure the gas cap is on tight, check under the hood for any hoses that may have come of around the air filter area. Most engine malfunction lights turn on due to emission control system malfunctions, it may be an O2 sensor or something simple like that. To find out exactly we'll need some diagnostic code information, most of the national autoparts chain stores can help you get the codes for you at no charge (exc ca) they connect the code reader and give you a printout and may offer some suggestions for you but please contact me back so I can help you figure out how to fix this, just go to an Autozone, O Reilly etc and they can help you then let me know what they found.
The airbag light is a seperate issue and it should be diagnosed using a diagnostic scanner that can access that particular system.
