Product Description

The 2001-2003 Toyota Highlander Air Fuel Ratio Sensor operates in conjunction with the vehicle's data processor to decide whether the fuel vapor going to the motor requires to be altered. The Air Fuel Ratio Sensor calculates the air and fuel levels in the engine, keeping them balanced for perfect operation. Denso Air and Fuel Ratio sensor, designed to detect the amount of the exhaust gas air and fuel ratio, is constructed from durable material that is corrosion and abrasion resistant. This sensor features zirconia solid electrolyte integrated with alumina heater substrate, which precisely controls the amount of oxygen concentration that flows into the diffusion layer to limit current flow. This sensor can easily be installed and ensures longevity.


  • Tarnish-proof platinum electrodes provides longer life and maintains accuracy
  • Quick-response planar zirconia element can quickly detect oxygen concentration
  • Measures A/F ratios from approximately 12:1 to 19:1
  • Increased performance by mapping a/f ratios throughout rpm range
  • Reduces emissions by keeping the air-fuel mixture at an optimum ratio
  • Reduced fuel consumption and maximizes catalytic converter life
