Product Details

The NGK 23142 (NTK) oxygen sensor, also called an O2 sensor or air-fuel ratio sensor, is a direct-fit replacement designed to meet OE requirements. It is a downstream sensor for position B1S2 (cylinders 1-3). It gives the engine control unit constant feedback on exhaust oxygen content. The ECU uses that signal to regulate the air-fuel ratio and to flag fuel delivery or catalytic converter efficiency problems through the OBD-II system.

Key Features:

  • Direct fit design: comes with an OE-specified connector and harness, so no splicing is needed
  • Position: downstream, B1S2 (cylinders 1-3)
  • Thimble-type ceramic element: becomes electrically conductive at high temperature and sends voltage signals to the engine management system
  • Platinum-coated sensing element: built for durability, and each sensor is individually tested
  • Fast heat-up: helps improve fuel economy and reduce emissions
  • Wire harness length: 13.5 in. (342.9 mm), 4 wire leads
  • Thread diameter: 18 mm (0.71 in.), screw-in installation
  • OE cross-references: 56041847AA, 56041953AA
  • Included: oxygen sensor and installation instructions

NTK is a leading supplier of OEM oxygen sensors. A fresh sensor helps restore proper fuel control, drivability and emissions performance.
