If the Service Engine Soon or Check Engine light turns on while you're driving, it means that there is a problem with your car's engine or emissions system. The light may be on for a variety of reasons, including:

      • A loose gas cap
      • A bad oxygen sensor
      • A misfiring spark plug
      • A problem with the fuel injection system
      • A problem with the emissions control system

In some cases, the light may come on for a minor problem that does not need to be addressed immediately. However, in other cases, the light may come on for a more serious problem that could damage your car if it is not repaired.

If the light comes on while you're driving, it is important to pull over to a safe location and turn off your engine. Once your engine has cooled down, you can start it back up and see if the light goes off. If the light stays on, you should take your car to a mechanic as soon as possible to have the problem diagnosed and repaired.

Here are some tips to help you stay safe if your check engine light turns on while you're driving:

      • Pull over to a safe location as soon as possible.
      • Turn off your engine and wait for it to cool down.
      • Do not restart your engine until you have had it diagnosed and repaired.
      • If you are unable to pull over to the side of the road, you can continue driving for a short distance, but only at a reduced speed.

It is important to remember that a check engine light is a warning sign. If you ignore it, you could damage your car and put yourself and others at risk.

Here are some of the signs that you should take your car to a mechanic immediately if the check engine light comes on:

      • The car is making strange noises.
      • The car is losing power.
      • The car is overheating.
      • The car is running rough.

If you see any of these signs, it is important to take your car to a mechanic as soon as possible to have the problem diagnosed and repaired. Ignoring these signs could lead to more serious problems down the road.
