Infiniti M45 ABS Wheel Speed Sensor in US

Your Infiniti M45 ABS wheel speed sensor is the component that makes anti-lock braking possible on your M45. It monitors the rotational speed of each wheel in real time and sends that data to the Infiniti M45 ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your M45, your ABS loses the input it needs. On wet, icy, or gravel road surfaces, the difference between a controlled stop and a skid can come down to whether your Infiniti M45 wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Infiniti M45

The ABS wheel speed sensor on the Infiniti M45 is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your M45. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the M45 ABS module interprets as wheel speed. On most modern Infiniti M45 vehicles, this same data feeds the traction control system, electronic stability control, and electronic brake force distribution, making a functioning wheel speed sensor critical to the safe operation of multiple M45 systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Infiniti M45

• ABS warning light on your Infiniti M45 dashboard, the most common first indicator of a failing sensor
• Traction control or stability control warning light illuminated alongside the M45 ABS light
• ABS activating on your Infiniti M45 during normal stops at low speed where it should not engage
• Complete ABS deactivation on the M45, wheels lock under hard braking on wet or icy roads
• Speedometer on your Infiniti M45 reading erratically or dropping to zero at speed
• Fault codes in the C0035 to C0050 range stored in the Infiniti M45 ABS control module

Passive vs. Active ABS Sensors for the Infiniti M45

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Infiniti M45. Passive sensors use an analog signal and are found on older M45 vehicles and many trucks still in service. Active Hall-effect sensors require a small power supply and output a clean digital signal, offering greater accuracy at very low speeds. Active sensors are standard on most Infiniti M45 vehicles manufactured after the mid-2000s and are required for full compatibility with modern M45 traction and stability control systems.

Why GeoBrakes for the Infiniti M45 ABS Wheel Speed Sensor

Signal accuracy matters as much as fitment with Infiniti M45 wheel speed sensors. A sensor that generates the correct frequency for your M45 ABS module ensures consistent ABS calibration, proper traction control thresholds, and accurate stability control response on your Infiniti M45. Every sensor in the GeoBrakes catalogue is matched to the Infiniti M45 through our vehicle selector, with front and rear positions listed separately to eliminate position errors on your M45.

Frequently Asked Questions - Infiniti M45 ABS Wheel Speed Sensor

Can I drive my Infiniti M45 with a faulty ABS wheel speed sensor?

You can drive the Infiniti M45 with a failed ABS sensor, but the anti-lock braking system on your M45 will be completely disabled. On icy or wet American roads, this significantly increases stopping distances and the risk of losing steering control during hard braking on your Infiniti M45. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Infiniti M45?

Use the GeoBrakes vehicle selector and enter the Infiniti M45 year, make, and model. The system displays only the sensors confirmed to fit the Infiniti M45, with front and rear positions listed separately. Select the position matching the sensor you are replacing on your M45 to avoid receiving the wrong unit.

Do I need to replace all four ABS sensors on my Infiniti M45 at the same time?

No. ABS wheel speed sensors on the Infiniti M45 are independent components and only the failed unit needs to be replaced. However, if your M45 has high mileage and one sensor has failed, it is worth visually inspecting the connectors on the other Infiniti M45 sensors for corrosion while the wheel is removed.
