Product Details

The NGK NTK 21039 oxygen sensor (also called an O2 sensor or lambda sensor) is an OE identical replacement that measures oxygen in the exhaust stream. It sends constant closed-loop feedback to the engine control unit (ECU). The ECU uses that signal to adjust the air-fuel mixture for good performance, fuel economy and emissions control.

Key Features:

  • OE identical design with an OE-type connector and attaching hardware for easy installation
  • 1-wire, unheated switching zirconia sensor with a 0-1 V signal range
  • Threaded mounting with an 18mm thread diameter
  • Dual-coated platinum element for fast response time and long service life
  • Protective coating and a corrosion-resistant housing shield the ceramic element from contaminants such as silicone and lead
  • Wiring harness included; the sensor bung is not included
  • Built to NTK OE specifications, with vibration and thermal shock testing during development

NTK is a leading supplier of original equipment oxygen sensors. A worn sensor can cause poor fuel economy, rough running, a check engine light, or oxygen sensor-related diagnostic trouble codes. Replacing it with the NTK 21039 helps restore proper air-fuel control, lower emissions and protect the catalytic converter.
