Rear Heated Oxygen Sensor – Essential for Clean Engine Performance

Why You Need This Sensor

The rear heated oxygen sensor helps monitor the oxygen level in your exhaust gases, ensuring your engine runs efficiently and keeps emissions low. It sends vital data to your car's ECU, helping adjust the fuel mixture for optimal combustion and fuel economy.

How It Works

Positioned after the catalytic converter, this sensor uses a built-in heater to reach operating temperature faster. It measures the amount of oxygen in the exhaust, giving real-time feedback to the engine management system. This keeps your fuel burning cleaner and improves engine life.

What Happens if It’s Broken

• Check engine light appears
• Poor fuel economy
• Rough engine operation
• Increased emissions and potential to fail inspection
• Catalytic converter damage risk
