Denso 234-4652 Oxygen Sensor - Downstream

Denso OE Style Oxygen Sensor 234-4652

Denso 234-4652 is an OE Style heated oxygen sensor built for exact replacement and first-time fit. It is engineered for downstream applications on select Chrysler, Dodge, and Mitsubishi vehicles, including Chrysler Sebring, Dodge Stratus, Mitsubishi Eclipse, and Mitsubishi Galant.

The OE Style line is designed to match original equipment fit and function, with a threaded mounting design, female connector, 4-wire configuration, and a 21.65-inch wiring harness length. This Denso oxygen sensor supports accurate exhaust feedback for vehicles that need a direct-fit downstream replacement.

Key Features

• Heated oxygen sensor for downstream placement
• Specific-fit design for direct replacement
• 4-wire configuration with female connector
• Threaded mounting type with 0.708-inch thread diameter
• 21.65-inch wiring harness length
• OE Style construction for factory-style fit and function

Detailed Description

Denso 234-4652 is manufactured and tested to OE standards for precise fitment and dependable operation. The sensor uses Denso’s aluminum oxide trap layer to help protect the ceramic element from silicone and lead contamination, supporting stable engine management and long service life. This makes it a practical choice for drivers replacing a downstream oxygen sensor on a 2001-2005 Chrysler Sebring, 2001-2005 Dodge Stratus, 2001-2005 Mitsubishi Eclipse, or 2001-2003 Mitsubishi Galant. It also applies to 2000 Mitsubishi Eclipse and 1999-2000 Mitsubishi Galant California exempt part applications.

This part cross-references Bosch 13796 and NTK 23525 for the same application.

What It Helps Fix

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel feedback from a worn downstream sensor
• Reduced fuel economy caused by inaccurate exhaust readings
• Rougher engine operation tied to aging emissions sensors
• Failed emissions inspection due to sensor-related faults

Installation Notes and Tips

Verify the connector style, wire count, thread diameter, and downstream position before installation. This sensor is a specific-fit replacement, so matching the original routing and harness length helps ensure proper installation on Chrysler Sebring, Dodge Stratus, Mitsubishi Eclipse, and Mitsubishi Galant applications. Inspect the exhaust bung threads and connector condition before mounting the sensor.

Quality Assurance

Denso builds this OE Style oxygen sensor to strict original-equipment standards and tests each component for replacement accuracy and fit consistency. The design focuses on reliable sensor response, contamination resistance, and long-term durability in emissions control service.
