Mercedes-Benz W209 CLK-Class Yaw Rate Sensor (ESP) - Used Original Parts

Description

Product Title

Mercedes-Benz W209 CLK-Class Yaw Rate Sensor (ESP) - Used Original Parts

Diagnosis and Common Symptoms

The Yaw Rate Sensor on the W209 CLK-Class is a critical component of the Electronic Stability Program (ESP), measuring lateral acceleration and rotational movement around the vertical axis of the vehicle. When this sensor fails or drifts out of calibration, the instrument cluster typically illuminates the ESP warning light and, in many cases, the ABS warning light simultaneously due to their shared CAN-bus communication. Common fault codes associated with sensor failure include C1234 (Yaw Rate Sensor Signal Faulty), C1235 (Sensor Supply Voltage Fault), and C1238 (Sensor Sensitivity Error). Drivers often report a "ESP BAS" message on the dash, a noticeable stiffening of the steering wheel at low speeds, or the ESP system engaging erratically even on dry, straight roads. In more advanced failure stages, the vehicle may enter a restricted "limp mode" for stability control, disabling active steering assistance and traction management until the fault is cleared.

Introduction

This listing is for a Genuine Used Yaw Rate Sensor sourced directly from a Mercedes-Benz W209 CLK-Class donor vehicle. As an M.S. Motor certified technician, I have personally Tested this unit on a bench diagnostic rig to confirm signal accuracy and voltage output prior to listing. Unlike aftermarket alternatives that often cause calibration conflicts, this Genuine part guarantees seamless integration with your existing ESP module. Every unit undergoes rigorous inspection to ensure it meets the original manufacturer specifications for safety and reliability.

Frequently Asked Questions

Q: What symptoms indicate failure? A: The most common indicators are an illuminated ESP and ABS warning light on the dashboard, a stiff or heavy steering feel at low speeds, and unexpected activation of the traction control system on flat, dry roads.

Q: Does this require coding? A: In most cases, a direct swap with a matching part number will be recognized by the vehicle's control module. However, we recommend a basic calibration check using STAR diagnostics (or equivalent) after installation to ensure the zero-point reading is accurate for your specific vehicle.

Q: Is this original? A: Yes, this is a 100% Genuine Mercedes-Benz part removed from an original W209 CLK-Class vehicle. It is not an aftermarket reproduction.
