Denso OE Style Oxygen Sensor 234-4018

Denso 234-4018 is a heated oxygen sensor built to OE-style specifications for direct replacement on a wide range of GM vehicles. It is designed for exact fitment on applications such as Chevrolet Silverado 1500, GMC Sierra 1500, Buick Regal, and Pontiac Grand Prix, with coverage across upstream, downstream, and downstream right positions.

Key Features

  • Heated oxygen sensor with a specific-fit design for direct replacement
  • 4-wire configuration with a female connector
  • Threaded mounting with 0.708 in. thread diameter
  • 15.35 in. wiring harness length for OE-style routing
  • Built and tested to OE standards for consistent sensor performance
  • Aluminum oxide trap layer helps protect the ceramic element from silicone and lead contamination

OE Style Construction

Denso’s OE Style line is engineered for first-time fit and factory-style replacement. The sensor element is precision built to match the original application, helping maintain accurate exhaust feedback for engine management. This part number, 234-4018, is used across many GM platforms and is a direct replacement choice when restoring oxygen sensor function on vehicles like the Chevrolet Impala, GMC Yukon, and Cadillac Escalade.

This part cross-references Bosch 13474 and NTK 21539 for the same application.

What This Oxygen Sensor Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel mixture readings from a failing sensor
  • Reduced fuel economy caused by inaccurate exhaust feedback
  • Rough idle or drivability issues tied to sensor degradation
  • Slow sensor response from contamination or age

Installation Notes and Tips

Verify the sensor position before ordering, since this application includes upstream, downstream, and downstream right locations. Confirm the connector style, wire count, and threaded mounting match the original sensor on your vehicle. For best results, inspect the harness routing and exhaust threads before installation, and use the vehicle’s service information for torque and connector placement.

Quality Assurance

Denso manufactures and tests this oxygen sensor to strict OE standards for fit, function, and durability. The OE-style design and contamination-resistant trap layer support reliable operation across the listed GM fitments, including Buick LeSabre, Chevrolet Monte Carlo, and Pontiac Firebird applications.
