The Check Engine Light (also known as the Malfunction Indicator Lamp) is a signal from the car’s engine computer that something is wrong. It can come on for various reasons such as a malfunctioning sensor, a problem with the exhaust system, a misfiring engine, problems in fuel efficiency, a loose gas cap, or even due to failure in the car’s electronic systems or mechanical components. To understand the exact issue, the car should be diagnosed using a professional scan tool that can read the specific error code stored in the car’s computer, and then necessary steps should be taken to fix the problem. Until then, the light will continue to illuminate as a warning sign.

If the sensors are not functioning correctly, your car will burn more fuel than necessary. 2. Gas Cap is Loose or Missing: A missing or loose gas cap can cause fuel to evaporate, prompting the check engine light to come on. 3. Catalytic Converter Failure: This part of your car reduces emissions from your vehicle’s exhaust, and if it’s failing it could decrease your gas mileage or make your car stall when you accelerate. 4. Spark Plugs or Plug Wires Need to be Replaced: These parts ignite the air and fuel mixture in your car’s engine. If they’re not functioning properly it can cause the engine light to trigger. 5.

Q what is engine backfire

Engine backfire is a phenomenon where combustion of fuel occurs outside the engine’s combustion chamber, producing a loud bang or pop sound. This usually happens when unburned fuel in the exhaust system ignites. It can occur in both carbureted and fuel-injected engines, often due to timing issues, rich fuel mixture, or faulty ignition components. Though backfire itself may not damage the engine immediately, it signals potential problems that need addressing. Regular maintenance and ensuring fuel systems and ignition components are in good working order can help prevent backfiring. While it might seem alarming, understanding its causes can aid in timely intervention, preventing more severe engine damage.
