What Is an O2 Sensor?
An oxygen sensor, often called an O2 sensor, is a crucial component of a vehicle’s exhaust system. It measures the amount of oxygen in the exhaust gases and helps the engine maintain optimal fuel efficiency and reduce harmful emissions. Most vehicles have multiple O2 sensors placed before and after the catalytic converter to ensure accurate readings.
Role in Emissions Control
O2 sensors monitor the air-fuel ratio in the engine, ensuring that it burns fuel efficiently while minimizing harmful emissions. A faulty sensor can lead to poor fuel efficiency, increased emissions, and engine performance issues.
Why O2 Sensors Are Valuable
O2 sensors are valuable for scrap because they contain precious metals, primarily platinum, which is used in the sensor’s tip. Platinum is a highly valuable metal commonly used in catalytic converters and other automotive components:
- Platinum-Tipped Elements: The platinum content in O2 sensors makes them a sought-after item for recyclers.
- Often Overlooked: Many people discard old O2 sensors without realizing their value.
Standard Vehicles with Valuable O2 Sensors
While almost every vehicle has O2 sensors, some models have sensors with higher precious metal content, making them more valuable for recycling. These include:
