SENSOR ASSY-OXYGEN

Reliable Oxygen Sensor for Clean Fuel Control ⛽?

This oxygen sensor is a key part of the exhaust feedback system. It is needed to help the engine computer keep the air/fuel mix correct in real time. When the mixture is right, you get smoother driving, better fuel economy, and lower emissions.

How It Works ⚙️

The sensor reads the oxygen level in the exhaust stream and sends a signal to the ECU. The ECU then adjusts injector pulse and fuel trims to maintain an efficient burn. On many setups, the built-in heater helps it reach operating temperature fast, so control becomes accurate shortly after start-up.

What Happens If It Fails ?

A weak or dead sensor can cause rich/lean running, unstable idle, hesitation, higher fuel use, and a glowing check engine light. Long-term driving with wrong fueling may damage the catalytic converter and foul spark plugs, turning a small part into a big repair.

Common Signs of Trouble

• Rough idle or surging
• Fuel smell from exhaust
• Poor MPG
• Emission test failure
