Different Sensors Used In Modern Cars And Their Functions

Contemporary automobiles are packed with technology, making them more fuel-efficient and secure to drive. Multiple Electronic Control Units (ECUs) that regulate a vehicle’s various functions are possible in this age of electronics.

This article will examine the most common variety of automobile sensors and their functions taken into consideration while ascertaining car insurance prices.*

1. Oxygen Sensors

The optimal air-to-fuel ratio for an internal combustion engine to function efficiently is 14.7:1. This indicates that 14.7 grammes of air must be present in the combustion chamber to consume one gramme of fuel. Oxygen sensors, also referred to as O2 sensors, detect the presence of oxygen in the exhaust pipes of motor vehicles. This information is communicated to the ECU, which modifies the air-to-fuel ratio to ensure the engine operates as efficiently as possible. 

2. Coolant Level Sensor

To prevent the engine from overheating, coolants are circulated through it. The coolant level sensor is either located at the bottom of the radiator or inside the expansion tank, and it activates a warning indicator if the coolant level falls below a predetermined threshold. Bajaj Allianz car insurance recommends ensuring that this sensor is working correctly. Use only the coolants the manufacturer recommends to ensure optimal cooling performance and reduce the risk of engine overloading. 

3. Engine Oil Level Sensor

Maintaining the correct quantity of engine oil per the manufacturer’s instructions is essential for preventing catastrophic engine damage. Inadequate amounts of engine oil can result in decreased lubrication levels within the internal components of an internal combustion engine (ICE), leading to significant wear and strain. This increased friction between moving elements can cause the engine’s temperature to rise to the point where it seizes. 

4. Engine Oil Pressure Sensor

All ICE engines use forced lubrication systems to ensure that engine lubricant reaches every nook and cranny of the engine, allowing for smooth operation and extending the engine’s lifespan by preventing metal-on-metal contact. The engine oil pressure sensor is typically located at the base of the cylinder head and is linked to the dashboard engine oil warning lamp. It may also be connected to the check engine light on certain automobiles. 

5. The sensor of mass airflow (MAF)

The mass airflow sensor is a component of the vehicle’s air intake system that measures the air volume entering the intake. The ECU uses this information to gauge the quantity of fuel that must be injected to achieve optimal combustion. It is generally situated between the intake filter and the intake manifold. If the MAF sensor on a vehicle fails, the ECU will be unable to determine the amount of fuel to let into the combustion chamber, resulting in poor engine performance. This may affect your insurance quote. Check a car insurance calculator to know more.*

A good insurance policy, like Bajaj Allianz car insurance, can protect your finances if your vehicle is involved in an accident and requires expensive repairs, just as sensors can help prevent catastrophic car malfunctions.
