Denso OE Style Oxygen Sensor 234-4253

Denso 234-4253 is an OE-style heated oxygen sensor built for specific applications on the Chevrolet Caprice and Pontiac G8. It is engineered for direct replacement fitment, accurate exhaust feedback, and dependable operation in downstream sensor locations.

Key Features

  • Heated oxygen sensor for downstream exhaust monitoring
  • Specific-fit design for direct replacement installation
  • 4-wire configuration with female connector
  • Threaded mounting type with 0.708 in. thread diameter
  • 12.28 in. wiring harness length
  • OE-style construction for exact replacement fit

OE Style Construction

Denso’s OE Style line is built to match original equipment fit and function for the listed applications. This oxygen sensor uses precision-built components and an aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and long service life. The Denso 234-4253 is a direct-fit replacement for downstream sensor locations on 2011-2014 Chevrolet Caprice and 2008-2009 Pontiac G8 models.

This part cross-references ACDelco 213-4325 and Bosch 18032 for the same application.

What This Sensor Helps Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel feedback from a worn downstream sensor
  • Reduced fuel efficiency caused by inaccurate exhaust readings
  • Slow or inconsistent sensor response in the exhaust stream
  • Replacement needs for OE-style downstream sensor service

Installation Notes

Verify the connector style, thread diameter, and downstream position before installation. This sensor is a specific-fit, threaded replacement with a female connector and 4-wire layout, so it should be matched to the original sensor location and harness routing on the vehicle. For 2011-2014 Chevrolet Caprice, downstream; for 2008-2009 Pontiac G8, downstream.

Quality Assurance

Denso manufactures and tests this oxygen sensor to OE standards for fit, function, and durability. The design focuses on first-time fitment and consistent performance in the listed Chevrolet Caprice and Pontiac G8 applications.
