How to Turn Off Engine Light

If the engine light comes on, it is important to have it checked out by a mechanic as soon as possible. However, there are some things you can do to try and turn off the engine light yourself.

Check the gas cap. Make sure the gas cap is on tight. A loose gas cap can cause the engine light to come on.
Check the oxygen sensor. The oxygen sensor is responsible for measuring the amount of oxygen in the exhaust. A faulty oxygen sensor can cause the engine light to come on.
Check the spark plugs. The spark plugs are responsible for igniting the fuel in the engine. Bad spark plugs can cause the engine light to come on.
Check the spark plug wires. The spark plug wires connect the spark plugs to the ignition coil. Worn out spark plug wires can cause the engine light to come on.
Check the catalytic converter. The catalytic converter is responsible for reducing emissions. A faulty catalytic converter can cause the engine light to come on.
Check the exhaust system. The exhaust system is responsible for removing exhaust gases from the engine. A faulty exhaust system can cause the engine light to come on.
Check the evaporative emissions system. The evaporative emissions system is responsible for preventing fuel vapors from escaping into the atmosphere. A faulty evaporative emissions system can cause the engine light to come on.
Check the engine control module. The engine control module is responsible for controlling the engine. A faulty engine control module can cause the engine light to come on.

If you are unable to turn off the engine light yourself, it is important to have it checked out by a mechanic as soon as possible.

Consequences of Ignoring Engine Light

Ignoring the engine light can lead to serious problems, including:

Reduced fuel economy
Increased emissions
Engine damage
Transmission damage
Failed emissions test

If you see the engine light on, it is important to have it checked out by a mechanic as soon as possible. Ignoring the engine light can lead to serious problems and costly repairs.
