The "Check Engine" light in a Toyota Camry indicates that there's a problem with the electronic engine control, electronic throttle control or electronic automatic transmission control systems. The problem can be specifically diagnosed by use of a code scanner; however, the light can sometimes be triggered by simple, easy-to-fix issues, such as low fuel or a loose fuel cap.
A "Check Engine" light on a Toyota Camry may indicate a number of problems with the car's electrical systems. The vehicle should be inspected as soon as possible by a qualified mechanic, who can scan the diagnostic system of the car to pinpoint the specific problem. However, until that can be done, the driver should do the following:
- Investigate whether any other dashboard indicators point to a serious problem, such as overheating or low oil levels. In this case, the car should be taken to a service or repair shop immediately.
- Check whether the vehicle is low on gas and, if so, refill the gas tank.
- Check whether the fuel cap is secured tightly. If a loose cap was the source of the problem, the light might not turn off until a few trips later.
- If the light comes on while the vehicle is losing power under an unusually heavy load, lighten the load and reduce the speed, if possible.
