OE Style Line Details

Denso’s OE Style product line focuses on direct replacement parts that mirror original sensor fitment and connection geometry. 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. If you need a Denso 234-4756 oxygen sensor for a Chrysler Aspen, Dodge Dakota, Dodge Durango, Mitsubishi Raider, or Chrysler Pacifica application, this OE-style design is intended to match the original installation point and electrical interface.

This part cross-references Bosch 13775 and NTK 23527 for the same application.

What This Oxygen Sensor Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel mixture readings
• Reduced fuel economy from a failing upstream or downstream sensor
• Slow sensor response affecting emissions control
• Hard-to-match replacement issues on specific-fit applications

Installation Notes and Tips

Verify the sensor position before ordering, since this part is listed for downstream and upstream applications depending on vehicle and engine configuration. Confirm the connector style, wire count, and threaded mounting dimensions against the original sensor. For best results, inspect the harness routing and connector condition before installation, and clear diagnostic trouble codes after replacement if required by the vehicle.
