Step-By-Step Guide: How To Replace The Rear ABS Speed Sensor On A Chrysler 300

By Nick Marchenko, PhD

Dear enthusiasts of automotive maintenance and guardians of the venerable Chrysler 300, today we embark on a rather intriguing journey into the realm of ABS speed sensor replacement. This guide is tailored for the 2015 Chrysler 300, a splendid machine that demands our utmost respect and care. We shall focus on the right-hand side, though it's worth noting the procedure mirrors the left with minor differences in wiring layout.

Preparation and Safety

First and foremost, safety and preparation are paramount. Begin by elevating your chariot with grace, removing the tire to reveal its inner workings, and securely placing it upon a jack stand. This exposes the ABS wheel speed sensor, a crucial component that, when rebellious, triggers various codes within your vehicle's diagnostic system. Should you encounter such codes, a trusty code reader will be your best ally, pinpointing the rebellious sensor with precision.

In our previous tales, we've discussed various elements of the Chrysler 300 that might also require your attention. Consider reading our guides on replacing the window regulator motor, or perhaps you'd find interest in replacing the engine oil and filter. Each guide offers wisdom to ensure your Chrysler remains in peak condition.

Locating and Removing the ABS Speed Sensor

The ABS wheel speed sensor sits nobly at the rear of the hub, guarded by a 10mm bolt that requires a gentle yet firm touch to remove. Once the bolt is relinquished, you may encounter a tab or connector that resists your advances. Fear not, for patience and a slight squeeze will see it release its grip, allowing you to withdraw the sensor from its throne.

The Unhooking of the Connector

As you delve beneath your Chrysler, you'll find a connector that snaps open with ease, revealing the path to liberate the sensor's wiring. This quest may lead you to encounter a plastic piece, potentially part of your new sensor's domain. Should this be the case, your focus should shift to ensuring this new realm is prepared for its inhabitant.

Reassembly: The Homeward Bound

With the old sensor vanquished, it's time to welcome the new. Reverse the disassembly process with reverence, ensuring each connector and clip finds its place with a satisfying click. The red clip, a gatekeeper of sorts, requires a nudge backwards to secure the new sensor's lineage.

As you retrace the sensor's wiring, remember, this isn't just a process; it's a ritual. Each step, from securing the 10mm bolt to ensuring the wiring is snug and protected, is a testament to your dedication to your Chrysler 300.

In the grand scheme of vehicle maintenance, this task is but a chapter in your ongoing journey.
