Check Engine Light Replacement

The "Check Engine Light" informs a driver of mechanical issues, such as emmision-control malfunction, vacuum loss and even complete engine failure. Vehicles with a flashing "check engine light" might fail emission-standards tests in some states.

Replace

Taking apart the dashboard is required to access the bulb in the check-engine light. Completing this task is challenging on some older vehicles. Disabling the check-engine light should never be attempted; it is illegal due to emissions regulations.

Repair

A check-engine light is often often triggered by temporary problems. Once the light is on, it will generally stay on due to activated codes. Purchasing a device to clear these codes might sometims cause the light to turn off.

Testing

Failure of certain vehicle systems might cause a check-engine light to come on. Testing performed on these systems can reveal the source of the light. Checking the fuel or ignition system is usually required.
