Besides the various problems that this event can have, will the check engine do it’s role and illuminate?
Yes, the check engine light (CEL) will come on if the catalytic converter is stolen. The catalytic converter is a device that converts harmful emissions from your car’s exhaust into less harmful substances. When the catalytic converter is stolen, the engine computer detects that the emissions levels are higher than normal and triggers the CEL.
Here are some of the signs that your catalytic converter has been stolen:
- A loud, roaring engine: The catalytic converter helps to reduce noise from the exhaust, so if it’s gone, your engine will be louder.
- Poor fuel economy: The catalytic converter helps to improve fuel economy, so if it’s gone, you’ll notice that your car isn’t getting as good of mileage.
- A smell of exhaust fumes: The catalytic converter helps to remove harmful emissions from the exhaust, so if it’s gone, you may notice a smell of exhaust fumes inside the car.
- A check engine light: The engine computer will detect that the catalytic converter is missing and trigger the CEL.
If you think your catalytic converter has been stolen, you should have it replaced as soon as possible. Not only will this fix the problem and get rid of the CEL, but it will also improve your car’s performance and fuel economy.
Here are some tips to prevent your catalytic converter from being stolen:
- Park in well-lit areas: Park your car in well-lit areas, such as garages or parking garages. This will make it more difficult for thieves to steal your catalytic converter.
- Use a catalytic converter shield: A catalytic converter shield is a metal cage that surrounds the catalytic converter and makes it more difficult to remove.
- Label your catalytic converter: Engrave your VIN number or other identifying information onto the catalytic converter. This will make it easier for police to identify your stolen catalytic converter.
