Detailed Product Description and Attributes

This Walker Products OE oxygen sensor (part number 250-241042) features a heated sensor type that allows for faster warm-up times and improved fuel efficiency. The sensor includes a 4-wire configuration with 20-gauge wiring, providing stable signal transmission and durability under high-temperature conditions. The wiring harness length of 18.5 inches offers flexibility during installation, while the radiused polygon male connector ensures a secure and corrosion-resistant connection. The sensor mounts via a threaded design with an 18.0 mm thread diameter, compatible with the exhaust system of specific Acura and Honda models such as the Civic, Civic del Sol, NSX, and TL. The overall length of 19.61 inches supports proper positioning within the exhaust stream for accurate oxygen level detection.

Walker Products OE Brand Line Information

The Walker Products OE line focuses on delivering original equipment quality parts that meet or exceed factory specifications. This oxygen sensor is part of that line, ensuring compatibility and performance consistent with the original sensor installed on Acura and Honda vehicles. Using a Walker Products OE sensor helps maintain emissions compliance and engine efficiency by providing reliable sensor data to the vehicle’s engine control unit.

Common Applications and Issues Addressed

  • Restores accurate air-fuel ratio readings for improved engine performance
  • Helps resolve check engine light triggers related to oxygen sensor faults
  • Reduces emissions by ensuring proper catalytic converter function
  • Prevents rough idling and poor fuel economy caused by faulty sensors
  • Supports smooth acceleration and engine responsiveness

Installation Notes and Tips

Installation requires removal of the old oxygen sensor and threading the Walker 250-241042 sensor into the exhaust manifold or pipe. Ensure the connector matches the vehicle’s wiring harness and that the sensor is tightened to manufacturer torque specifications.
