Toyota Prius Oxygen O2 Sensor

High-Precision Re-conditioned Oxygen Sensors for Toyota Prius – Calibrated to OEM Standards in Japan

For Toyota Prius owners in Sri Lanka, the oxygen (O₂) sensor—also known as the lambda sensor—is essential for maintaining the perfect balance between fuel economy, performance, and ultra-low emissions. This advanced sensor monitors oxygen levels in the exhaust gases and relays instant feedback to the Engine Control Unit (ECU). The ECU then fine-tunes fuel injection and ignition timing to sustain the optimal 14.7:1 air–fuel ratio under varying driving conditions.

Over time, an oxygen sensor’s accuracy can deteriorate due to electrode wear, contamination from fuel additives, or repeated thermal cycling. A worn sensor may send inaccurate readings, leading to poor fuel economy, unstable idle, higher emissions, and even catalytic converter damage if left unresolved.

We supply genuine, reconditioned OEM Toyota Prius oxygen sensors directly from Japan. Each sensor is restored using precision ultrasonic cleaning, heater element verification, and voltage response calibration—ensuring performance that meets or exceeds Toyota factory standards.
