Upstream Front O2 Lambda Sensor for Toyota Yaris
Upgrade your Toyota Yaris and compatible Toyota/Lexus models with this upstream front O2 lambda sensor designed to monitor the exhaust oxygen level and precisely regulate the air–fuel ratio. By providing accurate feedback to the engine control unit, this sensor helps maintain efficient combustion, reduces emissions, and supports optimal fuel economy. The heater-enabled design warms up quickly for steady readings soon after startup, improving cold-start performance and drivetrain smoothness. With broad compatibility across multiple models—including TOYOTA YARIS, 4RUNNER, AVALON, CAMRY, SEQUOIA, TACOMA, TUNDRA and Lexus ES350 (2019–2024)—you can trust a correct fit that supports consistent sensor performance.
Benefits & Tips
- Faster warm-up for reliable readings: The heating-type design reduces engine idle fluctuations during cold starts, helping keep the air–fuel ratio balanced sooner.
- Improved fuel efficiency and lower emissions: Accurate upstream O2 data helps the ECU adjust fueling precisely, contributing to steadier fuel consumption and cleaner exhaust.
- Peace of mind during maintenance: Replace a failing sensor with this unit to prevent recurring check engine light issues and protect catalytic converter health over time.
