Main Description

The Upstream Lambda Oxygen Sensor for Acura ILX, RDX, TLX and TSX is a precise, heated O2 sensor designed to keep your vehicle’s engine management in optimal balance. Crafted by IWOKPHD, this upstream (pre-cat) sensor continuously monitors exhaust gas oxygen levels and feeds real-time data to the engine control unit, enabling accurate fuel trims, smoother idle, and consistent performance. A healthy upstream sensor helps improve fuel efficiency, reduce emissions, and protect your catalytic converter by preventing rich or lean conditions.

Built to fit a broad range of Honda and Acura models from 2007 through 2022, this sensor uses a reliable piezoelectric sensing element and an integrated heating circuit for rapid warm-up, delivering stable readings even in cold starts. With multiple OEM part numbers listed, this sensor is designed to align with your vehicle’s original specifications and electrical connector configuration. Always verify the part number against your vehicle’s original part to ensure a perfect fit.

Benefits & Tips

  • Restore proper air-fuel ratio: Replacing a failing upstream O2 sensor helps prevent overly rich or lean fuel trims, improving throttle response and overall drivability.
  • Boost efficiency and emissions: Accurate oxygen readings support efficient combustion, helping you achieve steadier MPG and cleaner exhaust.
  • Easy compatibility checks: Use the listed OEM numbers (e.g., 36531-5A2-A01, 36531RMEA01, 36531RWCA01, etc.) to confirm the correct fit for your specific Acura or Honda model within the 2007–2022 range.
