Product Details

This Denso oxygen sensor is engineered for the downstream position on the Ford Fiesta and is designed to match factory fitment and electrical requirements. The Denso OE Style line uses precision-built components for accurate replacement, and the sensor includes an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination. That protection supports stable engine management, fuel control, and long service life. This part number 234-4962 also cross-references Ford CV6Z9G444D for the same application.

Common Issues It Can Address

  • Check engine light related to downstream oxygen sensor faults
  • Incorrect exhaust oxygen readings affecting fuel trim
  • Reduced fuel economy caused by a failing sensor signal
  • Rough running or drivability concerns tied to emissions feedback
  • Emissions test failures caused by sensor degradation

Installation Notes

Fits 2014-2019 Ford Fiesta, downstream. Confirm connector style, harness routing, and exhaust location before installation. Because this is a specific-fit heated oxygen sensor, use the factory mounting point and verify the sensor is installed in the correct downstream position. The part number 234-4962 is intended for direct replacement on listed Ford Fiesta applications.
