Car All Sensor Name List and Their Functions

Introduction

When buying a car, it’s not just about how it looks or feels; knowing the technology inside matters too. Today’s cars use lots of sensors to keep things running smoothly and safely. If a sensor breaks, it can change the way your car is repaired because mechanics rely on these sensors to diagnose problems. Read on for a list of all car sensor names.

Car All Sensor Name List

Modern cars are packed with sensors that act like the vehicle’s senses. Here’s a simple guide to some of the most common sensors you’ll find:

• Oxygen Sensor:

This sensor checks the oxygen level in the exhaust. It helps the car maintain the perfect fuel-to-air mix so your engine runs efficiently and produces fewer emissions.

• Mass Air Flow (MAF) Sensor:

This sensor estimates the amount of air entering the engine. The car uses this information to determine the right amount of fuel to inject, keeping the engine happy and smooth.

• Intake Air Temperature (IAT) Sensor:

Air temperature matters because colder air has more oxygen. This sensor measures the temperature so the ECU can fine-tune the fuel mix for better performance.

• Engine Oil Sensor:

Your engine needs enough oil to run well. This sensor monitors oil levels and lights up a warning if they drop too low, saving you from costly damage.

• Vehicular Speed Sensor (VSS):

This one tracks how fast your wheels are turning. It helps systems like ABS brakes work properly to keep you safe, especially in tricky driving conditions.

• Tyre Pressure Monitoring System (TPMS):

Flat or underinflated tyres aren’t just dangerous, they waste fuel. The TPMS alerts you if a tyre’s pressure is low so you can fix it quickly.

• Coolant Temperature Sensor:

Engines can overheat, which is bad news. This sensor watches the coolant temperature and warns you if it’s getting too hot, so you can stop before trouble starts.

• Engine Knock Sensor:

Sometimes, the fuel-air mix ignites too early, causing a knocking sound that can damage the engine. This sensor detects this and tells the ECU to adjust the timing to protect your car.

• Airbag Sensor:

If there’s an accident, this sensor springs into action, deploying airbags and locking doors to keep you safe.

• NOx Sensor:

Cars have to control pollution, and this sensor measures harmful nitrogen oxides in the exhaust. It helps keep emissions in check so your car stays eco-friendly.

Conclusion

Knowing the types of car sensors allows you to look after your car better and drive more safely. Remember to also put additional security measures in place, such as a car insurance policy. This can offer financial protection should any car system fail or in other instances of damage or loss.
