Walker Products Aftermarket Line Details

This oxygen sensor is part of the Walker Products Aftermarket line, which focuses on providing replacement emission control components engineered to meet or exceed OEM specifications. The line emphasizes precise fitment and reliable sensor performance, making it suitable for maintaining factory-level emissions standards in Volvo vehicles.

Product Description and Technical Specifications

The Walker 350-33036 oxygen sensor features a heated sensor element that allows it to reach operating temperature quickly, improving fuel efficiency and reducing emissions during cold starts. The sensor’s 20-gauge wiring ensures consistent signal transmission, while the 63.31-inch wiring harness length and 66.85-inch overall length provide adequate reach for installation in the specified Volvo models. The threaded mounting type with an 18.0 mm diameter allows secure attachment to the exhaust system. The radiused polygon connector with both male and female ends ensures a proper and secure electrical connection, minimizing the risk of signal loss or corrosion.

Common Applications and Issues Addressed

  • Helps maintain proper air-fuel ratio for efficient combustion
  • Reduces engine misfires and rough idling caused by faulty sensors
  • Prevents increased emissions and failed emissions tests
  • Improves fuel economy by providing accurate oxygen level readings
  • Resolves check engine light triggers related to oxygen sensor faults

Installation Notes and Tips

  • Ensure compatibility with Volvo 240, 740, 760, 780, 940, and 960 models before installation
  • Use proper tools to avoid damaging the 18.0 mm threaded mounting
  • Check wiring harness routing to prevent contact with hot exhaust components
  • Verify connector polarity and secure connection of male and female ends
  • Allow the engine to cool before sensor removal or installation
