Delphi ES20175 Oxygen Sensor

Delphi ES20175 Oxygen Sensor Overview

The Delphi ES20175 is a heated oxygen sensor built for precise exhaust monitoring in a wide range of Mercedes-Benz and Chrysler Crossfire applications. With OE heritage from a supplier to major automakers, this sensor is engineered to support accurate air-fuel feedback and reliable emissions system performance.

Compatible With Mercedes-Benz CL600, S600, E350, SL500, and related models, the ES20175 is a direct-fit replacement for many front and rear sensor locations. It also cross-references Bosch 16123 for the same application.

Key Features

• Heated oxygen sensor for faster operating temperature and stable signal output
• 4-wire design for common OE-style engine management systems
• Round connector shape for vehicle-specific harness connections
• 18 x 1.5 mm thread size for proper exhaust bung fitment
• 470.0 overall length for application-specific routing
• Includes oxygen sensor and instruction sheet
• Fits front, rear, front left, front right, rear left, and rear right positions depending on vehicle application

Detailed Description

Delphi ES20175 oxygen sensor applications cover many Mercedes-Benz platforms, including CL600, S600, S65 AMG, SL600, E500, E320, ML500, and G500, along with Chrysler Crossfire. This part number, ES20175, is built around OE experience and aftermarket service knowledge to help maintain proper exhaust feedback for engine control systems. For shoppers searching for a Mercedes-Benz oxygen sensor front left, rear right oxygen sensor for Chrysler Crossfire, or a heated 4-wire O2 sensor for Mercedes-Benz E-Class and S-Class models, this part provides a focused fitment match.

This part cross-references Bosch 16123 for the same application.

What It Is Used For

• Replacing a failed oxygen sensor that triggers check engine light concerns
• Restoring accurate exhaust oxygen readings for fuel control
• Addressing poor idle quality or drivability issues tied to sensor signal loss
• Correcting emissions-related fault codes from aging upstream or downstream sensors
• Servicing front or rear sensor locations on supported Mercedes-Benz and Crossfire vehicles

Installation Notes and Tips

Verify the exact position on your vehicle before ordering, since ES20175 is used in multiple front and rear locations. Confirm thread size, connector shape, and wire routing against the original sensor, and use the application tab for position-specific fitment on your Mercedes-Benz or Chrysler Crossfire. Inspect the exhaust bung and harness connector before installation to ensure a proper seal and secure electrical connection.

Quality Assurance

Delphi builds this sensor with OE heritage and decades of supplier experience supporting major automakers, bringing factory-level design knowledge to the aftermarket replacement part.
