Denso 234-4656 Oxygen Sensor

OE-Style Oxygen Sensor for Mitsubishi and Chrysler Applications

Denso 234-4656 is an OE-style heated oxygen sensor built for direct replacement in select Mitsubishi, Chrysler, and Dodge applications. It is designed for specific-fit installation with a 4-wire male connector, threaded mounting, and a 29.53-inch wiring harness for the listed downstream and upstream positions.

For drivers searching for a downstream oxygen sensor for Mitsubishi Outlander, Eclipse, Galant, or Montero applications, this Denso sensor is built to match the original fit and electrical layout. The Denso 234-4656 also serves as a direct-fit option for select Chrysler Sebring and Dodge Stratus models.

Key Features

• Heated oxygen sensor for precise exhaust feedback
• Specific-fit design for the listed vehicle applications
• 4-wire configuration with male connector
• Threaded mounting type with 0.708-inch thread diameter
• 29.53-inch wiring harness length
• OE-style replacement from Denso

Built to OE Standards

Denso’s OE Style line is engineered for exact replacement and first-time fitment. This oxygen sensor is precision built and tested to OE standards, with an aluminum oxide trap layer that helps protect the ceramic element from silicone and lead contamination. That construction supports stable engine management, consistent fuel control, and long service life in demanding exhaust environments.

This part cross-references NTK 23521 and Bosch 13412 for the same application.

What It Helps Address

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

Installation Notes

Verify the sensor position before ordering, since this part is listed for downstream left, downstream rear, downstream right, downstream, and upstream left locations depending on the vehicle. Confirm connector style, wire count, and thread size against the original sensor before installation. This Denso 234-4656 is a specific-fit replacement, so it should be matched to the exact year, make, model, and position shown in the fitment data.
