Product Details

This Denso oxygen sensor is manufactured and tested to OE standards, with precision-built dimensions for first-time fitment.

Common Issues It Can Help Address

  • Check engine light related to oxygen sensor performance
  • Incorrect air-fuel ratio readings from a worn upstream sensor
  • Reduced fuel economy caused by slow sensor response
  • Rough idle or drivability concerns tied to exhaust feedback errors
  • Failed emissions testing due to sensor degradation

Installation Notes and Tips

Verify upstream placement before installation and confirm connector style, thread diameter, and harness length match the original sensor. Because this is a specific-fit threaded sensor, proper routing and secure seating are important for accurate exhaust readings on the Chevrolet Spark. Always compare the old sensor to Denso 234-4765 before installation.
