Engine Sensors for your Jaguar

Engine sensors are responsible for monitoring various aspects of your car’s engine, such as temperature, pressure, and airflow. These sensors provide important data to the engine control unit, which uses that information to optimise the engine’s performance and prevent damage. Some common types of engine sensors include oxygen sensors, mass air flow sensors, and coolant temperature sensors.

With a focus on exceptional quality, our engine sensors guarantee extreme durability and resistance to wear, heightening your driving experience to new limits. Experience the perfect harmony of engineering excellence and driving satisfaction with SNG Barratt’s premium engine sensors. Browse our selection now and unlock the full potential of your Jaguar’s Engine!

What is an Oxygen Sensor?

The sensor works by generating a voltage signal that is proportional to the amount of oxygen in the exhaust gases. When the engine is running at its optimal air-fuel ratio, the voltage signal from the oxygen sensor is stable. However, if the air-fuel ratio is lean (more air than fuel), the voltage signal from the sensor will be low, and if the air-fuel ratio is rich (more fuel than air), the voltage signal will be high. The ECU uses this information to adjust the air-fuel ratio and keep the engine running at its optimal performance.

When a car’s engine is running, it produces exhaust gases that contain various pollutants. The oxygen sensor, also known as the O2 sensor, is a device that measures the amount of oxygen in the exhaust gases. It is located in the exhaust system of the car and sends signals to the engine control unit (ECU) to adjust the air-fuel ratio to optimize engine performance and reduce emissions.
