Bosch 15510 Oxygen Sensor

Bosch Oxygen Sensor 15510 Overview

Bosch Engineered Oxygen Sensor 15510 is a direct-fit narrow-band O2 sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management across changing engine loads, making it a practical replacement for Chrysler, Dodge, Jeep, Ram, and select Mercedes-Benz applications.

Fits 2021-2025 Chrysler Pacifica, upstream; Fits 2021-2025 Chrysler Voyager, upstream; Fits 2021-2025 Dodge Durango, upstream; and other confirmed upstream and downstream applications across the 2001-2025 model years.

Key Features

• Direct-fit oxygen sensor with specific vehicle application coverage
• Narrow-band sensor type for switching-style air-fuel feedback
• Heated design for faster closed-loop operation
• 4-wire configuration with included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Metal housing and high-temperature-resistant construction for demanding exhaust conditions
• Rectangle female connector with pin terminals for OE-style connection

Why Bosch Engineered Oxygen Sensor

Bosch has decades of OE oxygen sensor development behind this part number 15510. The Bosch Engineered Oxygen Sensor line builds on Bosch’s original oxygen sensor work and later planar narrowband designs, focusing on quicker light-off, accurate lambda feedback, and reliable closed-loop response. That makes this Bosch 15510 a strong OE-style replacement for vehicles such as the Chrysler 300, Dodge Charger, and Jeep Grand Cherokee where precise sensor input matters for drivability and emissions control.

This part cross-references Mopar 56028994AB and 56029049AA for the same application.

Common Problems This Sensor Can Address

• Check engine light related to oxygen sensor performance
• Rough idle or inconsistent fuel control from aging O2 sensor output
• Delayed closed-loop operation after cold start
• Poor emissions test results caused by inaccurate exhaust feedback
• Fuel trim issues tied to slow or unstable sensor switching

Installation Notes

Confirm the sensor position before ordering, since this part is used in multiple upstream and downstream locations depending on the vehicle. Verify connector shape, wire count, and thread size against the original sensor before installation. The threaded design and direct-fit harness help simplify replacement on confirmed applications such as the Ram 1500 Classic, Jeep Compass, and Mercedes-Benz SL63 AMG.

For best results, inspect the exhaust bung threads and wiring routing before installation, and clear diagnostic trouble codes after the repair if required by the vehicle.

Quality Assurance

Bosch supplies this oxygen sensor as an OE-proven replacement built to the same engineering standards that support original equipment applications. The sensor uses advanced ceramic elements, optimized heater control, and durable materials intended to maintain consistent performance under heat and vibration.
