Why did the check engine light come on


The check engine light usually comes on due to emissions issues. I'd bet that tank of gas was the culprit. Run it nearly empty and then fill up again. If it doesn't go out in a few days take it to an auto parts store and have them read the code. At that point my guess would be O2 sensors.

A bad gas cap will cause the light to come on, of so replace the cap. The vent is not working if gas is coming back at you. Replace with new.

My check engine light came on yesterday and after taking it to get the code , it was for the gas cap. I filled it up with gas and replaced the cap tightly. How do I get the light off.


It depends on the make and model of the vehicle. Some newer vehicles, once the car is driven with the cap loose, or the seal wears to the point of leaking pressure causing the light to come on, you must take it to the dealer or service center to get the light reset. You can try unhooking your negative battery cable for a few minutes to see if that erases the engine light.

The engine of my 2007 rav4 shuts down whilst driving once in a while. When it restarts, the check engine light and the VSC comes on. Also, the tire pressure light has been on for a while and I am unable...


OK try this: make sure the fuel filler cap is on tight. Toyota (and Lexus) checks the EVAP system for leaks and if it finds a fault it lights the CEL and VSC. If the fuel cap is loose or the rubber seal on it is cracked then this will be seen as EVAP leak. To clear the CEL etc disconnect the battery negative terminal for five minutes (you may have to enter the radio security code after this so have it available when you reconnect the battery).

This is a safety feature that the vehicle brings. You need to reset the E.C.U on dealership or it will keep doing it to you. It was probably caused by one single time that you did not closed the fuel cap correctly. Good luck
