Mercury Montego ABS Wheel Speed Sensor in US

Your Mercury Montego ABS wheel speed sensor is the component that makes anti-lock braking possible on your Montego. It monitors the rotational speed of each wheel in real time and sends that data to the Mercury Montego ABS control module, which uses it to prevent wheel lockup during emergency stops. When a sensor fails on your Montego, 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 Mercury Montego wheel speed data is reaching the module.

What Is the ABS Wheel Speed Sensor on Your Mercury Montego

The ABS wheel speed sensor on the Mercury Montego is an electromagnetic or Hall-effect sensor mounted near each wheel hub or bearing assembly of your Montego. It generates an electronic signal as a toothed reluctor ring rotates past it, producing a frequency the Montego ABS module interprets as wheel speed. On most modern Mercury Montego 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 Montego systems simultaneously.

Signs of a Failing ABS Wheel Speed Sensor on the Mercury Montego

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

Passive vs. Active ABS Sensors for the Mercury Montego

GeoBrakes stocks both passive and active ABS wheel speed sensors for the Mercury Montego. Passive sensors use an analog signal and are found on older Montego 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 Mercury Montego vehicles manufactured after the mid-2000s and are required for full compatibility with modern Montego traction and stability control systems.

Why GeoBrakes for the Mercury Montego ABS Wheel Speed Sensor

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

Frequently Asked Questions - Mercury Montego ABS Wheel Speed Sensor

Can I drive my Mercury Montego with a faulty ABS wheel speed sensor?

You can drive the Mercury Montego with a failed ABS sensor, but the anti-lock braking system on your Montego 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 Mercury Montego. Replacing a failed sensor promptly is strongly recommended, particularly before winter.

How do I find the right ABS sensor for my Mercury Montego?

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

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

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