Oxygen Sensors Buying Guide
Oxygen sensors, also known as O2 sensors, play a crucial role in the performance and efficiency of modern-day automobiles.
These sensors are responsible for measuring the amount of oxygen in the exhaust gases and sending this data to the engine’s computer, which then adjusts the air-fuel ratio for optimal combustion.
If you are in the market for an oxygen sensor for your vehicle, there are certain factors that you need to consider before making a purchase. This buying guide will help you navigate through the different types of oxygen sensors and make an informed decision.
#1. Type of Sensor
The first thing to consider when buying an oxygen sensor is the type of sensor that your vehicle requires. There are two main types of O2 sensors – heated and unheated.
Heated oxygen sensors have a built-in heating element that helps them reach the optimal operating temperature quickly. They are commonly used in newer vehicles, while unheated sensors are found in older models.
#2. Number of Sensors
The number of sensors your vehicle needs depends on its make and model. Some cars have multiple oxygen sensors, with one for each cylinder, while others may have just one for the entire exhaust system.
It is crucial to check your vehicle’s manual or consult a professional to determine the number of sensors needed.
