Product Details

The National Oil Seal 25592 is a 4-wire oxygen sensor designed to monitor exhaust gas composition and provide accurate feedback to the engine control unit (ECU). Operating within a standard 0–1 volt signal range, this sensor helps the ECU maintain optimal air/fuel mixture for efficient combustion, reduced emissions, and reliable engine performance.

Key Features:

  • 4-Wire Design: Includes an integrated heater circuit for faster sensor warm-up and stable readings across operating conditions
  • Signal Range: 0–1 V output for precise air/fuel ratio monitoring
  • Engine Displacement Compatibility: Designed for use with 2.0L, 2.3L, 3.0L, and 3.6L engine applications
  • Sold Individually: Includes one (1) oxygen sensor

A properly functioning oxygen sensor is critical to maintaining fuel efficiency and passing emissions inspections. The National Oil Seal 25592 is a direct-fit replacement intended to restore factory-level sensor performance.
