Why is the malfunction indicator light (MIL) on in my 911?

Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your 911’s malfunction warning light, or better known as the check engine light, to illuminate.

Can you clear the 911 check engine light on your own?

Resetting a malfunction warning light at home may be possible sometimes, but it is never recommended. The check engine light is commonly triggered by a misfire, fault or malfunction in one of the vehicle's systems. It is important to identify and fix the underlying problem to ensure the safety and reliability of the vehicle. Resetting the check engine light without addressing the underlying issue may temporarily remove the warning, but it will not fix the root cause of the problem.

Does my 911 transmission belong to the drivetrain system?

Yes, the transmission is an essential part of your 911’s drivetrain. The drivetrain consists of components — like the transmission — that transfer power from the engine to the wheels to move your 911 forward. Other components in the driver train include the axles, differential, and driveshaft.
