Hyundai Sonata Oxygen O2 Sensor

Re-conditioned Oxygen O₂ Sensors for Hyundai Sonata – Imported from Korea

For Hyundai Sonata owners in Sri Lanka, a properly functioning oxygen (O₂) sensor—also known as a lambda sensor—is crucial for maintaining engine efficiency and emission control. The sensor continuously measures the oxygen level in the exhaust gases and sends accurate data to the Engine Control Unit (ECU). Based on this information, the ECU fine-tunes the fuel-air mixture, ensuring smoother engine operation, improved fuel economy, and reduced harmful emissions.

Over time, oxygen sensors can lose accuracy due to heat, carbon deposits, and fuel contaminants. A failing sensor may deliver incorrect readings, causing the engine to run inefficiently—resulting in higher fuel consumption, rough idling, sluggish acceleration, and increased exhaust emissions.

We provide professionally re-conditioned oxygen sensors imported directly from Korea for Hyundai Sonata models in Sri Lanka. Each sensor is restored through deep cleaning, recalibration, and signal-response testing to ensure dependable performance and long-lasting durability.

Symptoms of a Faulty Oxygen Sensor:

Check Engine Light with error codes (P0130–P0167)

Noticeable drop in fuel efficiency (KPL decrease)

Engine hesitation or unstable idle

Strong fuel smell from exhaust

Higher carbon monoxide (CO) and hydrocarbon (HC) emissions

Driving for long periods with a defective O₂ sensor can also damage the catalytic converter, leading to expensive repairs.
