- The check engine light could indicate a problem with your vehicle's emissions control system, which can be dangerous and expensive to repair.
- The reduced speed light may indicate a problem with your vehicle's engine or transmission, which could also be dangerous and expensive to repair.
If your vehicle is out of warranty, you can try to fix the problem yourself. There are a few things you can check, such as:
- Ensuring your gas cap is on tight.
- Checking the engine air filter and replacing it if it's dirty.
- Checking the spark plugs and wires and replacing them if they're worn out.
If you've checked all of these things and the light is still on, you should take your vehicle to a mechanic for diagnosis.
Here are some additional tips for getting the check engine and reduced speed light off:
- Use high-quality fuel.
- Avoid driving in stop-and-go traffic.
- Drive at a steady speed whenever possible.
- Avoid idling for long periods of time.
If you can, it's best to have the problem diagnosed and repaired as soon as possible. Driving with the check engine and reduced speed light on can be dangerous and expensive.
