WJIECO 234-9056 Air Fuel Ratio Oxygen Sensor | 5-Wire Heated Wideband O2 A/F Sensor | Upstream OE 89467-07010 , 8946702040, 8946712030, 8946747010 Replacement for Toyota Camry RAV4 Lexus ES300 2.4L 3.0L | IATF 16949 Certified

1. Accurate measurement, meeting strict emission regulations:

The wideband planar sensing element delivers a broad linear measurement range (λ 0.65 to lean limit) with precision far exceeding conventional narrowband oxygen sensors, and can capture minute changes in air-fuel ratio across the entire operating range. The measurement error is ≤±3% of reading at λ=1, with fast temperature compensation response, which meets the requirements of Euro 5 and Euro 6 emission regulations and is perfectly adapted to the vehicle’s engine management system for precise fuel control.

2. Smarter Technology:

Designed for fit-and-forget convenience with OE-level calibration that adapts seamlessly to your vehicle’s ECU. Faster Response — third-party tests validate OE-level accuracy and responsiveness, ensuring swift and precise air-fuel mixture adjustment during acceleration and deceleration. Enhanced Durability — built to withstand harsh exhaust conditions with improved protection against oil, fuel, and water ingress, ensuring long-lasting reliability.

3. Premium Material and Performance:

The air fuel ratio sensor housing is made of high-grade stainless steel with excellent corrosion resistance and heat dissipation, ensuring fast response times and long-term stability. The sensing element utilizes planar zirconia ceramic technology with integrated heater and pump cell, offering exceptional thermal shock resistance and dimensional stability which can still provide accurate and reliable measurement results even in complex or harsh exhaust environments. Our sensor chip is engineered with a brand-new high-temperature planar ceramic core, delivering precise wideband detection. Designed for exceptional durability.

4. Effortless Installation:

Package including the sensor and OEM-style connector. The automotive A/F sensor is installed upstream of the catalytic converter in the exhaust manifold and can be installed easily and quickly with a single 22mm wrench or oxygen sensor socket. The air fuel ratio sensor seamlessly replaces older or faulty sensors while maintaining factory-spec signal output, making it a standard OEM replacement.

5. Stable compatibility and fault prevention:

Equipped with high-quality planar zirconia ceramic chips and waterproof seals, it is waterproof and dustproof, avoiding sensor failure caused by moisture and contamination; Stable signal transmission, eliminating problems such as rough idle, poor fuel economy, hesitation under acceleration, and constant check engine lights caused by air fuel ratio sensor failures.
