Imagine driving down the highway, enjoying the open road, when suddenly your car throws a check engine light. Panic sets in! You pull over, check the owner’s manual, and see the dreaded code “P0420 – Catalyst System Efficiency Below Threshold (Bank 1)”. You’ve heard it all before: “Cat converter!” But what exactly does that mean for your car, and how can a car scan tool help you figure it out?
Understanding Car Scan Tool Reads and the Cat Converter
Car Scan Tool Reads and OBD2 Codes:
A car scan tool, often called an OBD2 scanner, is a diagnostic tool used to read codes from a vehicle’s onboard diagnostic system (OBD). These codes, such as “P0420”, are standardized across various car manufacturers and provide valuable insights into potential issues within a car’s systems.
Cat Converter: The Heart of Emissions Control:
A catalytic converter is a vital component in your car’s exhaust system, responsible for reducing harmful emissions like carbon monoxide, hydrocarbons, and nitrogen oxides. It essentially acts like a filter, converting these pollutants into less harmful gases.
The Meaning of “Car Scan Tool Reads Cats”
The term “Car Scan Tool Reads Cats” is a slang term commonly used in the automotive community to describe situations where a scan tool indicates issues with the catalytic converter. This is because code P0420, which often pops up on car scan tools when the cat converter is malfunctioning, is often referred to as “CAT code” or “Cat code reader”.
Why Your Cat Converter Might Be Failing:
- Age and Wear: Like any part, cat converters can wear out over time, especially with high mileage.
- Fuel Issues: Improper fuel-to-air ratios caused by clogged injectors or faulty sensors can lead to excessive heat, damaging the cat converter.
- Misfires: Engine misfires can cause unburned fuel to enter the exhaust system, leading to heat buildup and damaging the cat converter.
How to Address Cat Converter Issues
When a scan tool reads “cats”, it’s important to address the problem. Here are some steps to take:
- Get a professional diagnosis: A qualified mechanic can use a scan tool to read the codes and determine the exact cause of the cat converter issue.
- Inspect the Cat Converter: The mechanic will visually inspect the cat converter for damage, blockages, or signs of overheating.
- Replace the Cat Converter: If the cat converter is damaged, it will need to be replaced. This is usually done by a qualified mechanic.
Frequently Asked Questions:
Q: What are the signs of a bad cat converter?
A: In addition to the check engine light, other signs include a decrease in fuel economy, a rattling noise from the exhaust system, and a noticeable decrease in engine power.
Q: Can I drive with a bad cat converter?
A: While it’s not ideal, you can drive a short distance with a bad cat converter. However, it’s best to get it repaired as soon as possible to prevent further damage to your car.
Q: How much does it cost to replace a cat converter?
A: The cost of replacing a cat converter varies depending on the make and model of your car. Some converters can be as cheap as $100, while others can cost upwards of $1,000.
