How many sensors are in a car engine? There are around 15-30 sensors in a modern car engine if you don’t include the solenoids. You can find over 70 sensors in a modern car if you count every sensor in the whole car. 1. Engine Oil Level Sensor Oil Level Sensor One of the most common sensors in your vehicle is the engine oil level sensor. This sensor measures the oil level in your engine oil pan to ensure that it’s at a safe operating capacity. If you don’t have enough oil, this sensor will cause an oil level warning light on your dashboard. This sensor is often installed on the bottom of the oil pan, so you need to tap out the engine oil to replace it. This depends on the engine model, though. 2. Engine Oil Pressure Sensor Oil Pressure Sensor The engine oil pressure sensor is often quite similar to the oil level sensor, except that it measures the oil pressure after the oil pump. You will often find this sensor located at the engine block, often near the fuel filter. T...
When it comes to your car’s exhaust system, the catalytic converter (often called the "catalyst") plays a crucial role in reducing harmful emissions. However, when it fails, it can lead to performance issues and even legal problems. In this blog post, we’ll explore **how a catalytic converter works** and **what happens when it goes bad**. What Does a Catalytic Converter Do? The catalytic converter is an essential part of your car’s exhaust system. Its main job is to **convert harmful pollutants into less harmful gases** before they exit the tailpipe. Here’s how it works: 1. Reduces Harmful Emissions The catalyst contains precious metals like platinum, palladium, and rhodium,which facilitate chemical reactions that break down pollutants: - Carbon monoxide (CO)→ Converted into carbon dioxide (CO₂) - Hydrocarbons (HC)→ Converted into water (H₂O) and CO₂ - Nitrogen oxides (NOx) → Broken down into nitrogen (N₂) and oxygen (O₂)* 2. Helps M...
