How does the Harley speed sensor work?

Inductive or optical sensors are frequently used as vehicle speed sensors. Inductive sensors are most frequently made up of a rod magnet on top of a magnetic pin that is encircled by a fixed coil. A ferromagnetic rotor with teeth is mounted a fixed distance away from this sensor. 

The magnetic flux in the coil changes as the rotor rotates and a tooth approaches the rod. A voltage pulse is produced across the coil as a result of the flux change. These voltage pulses are counted by the engine control module of the vehicle, which also determines the speed.

Typically, inductive or optical sensors are used to measure vehicle speed. A rod magnet sits atop a magnetic pin that is encircled by a fixed coil in the most typical inductive sensors. A fixed distance separates this sensor from a ferromagnetic rotor that has teeth. 

The magnetic flux in the coil shifts as the rotor rotates and a tooth moves in close proximity to the rod. An electrical pulse travels across the coil as a result of this flux change. These voltage pulses are counted and the vehicle’s speed is calculated by the engine control module.

What are the symptoms of a failing Harley speed sensor?

As we’ve mentioned, the following are the most common symptoms of a failing speed sensor. So if your vehicle is showing one or more of these symptoms, you have to notice that there is something wrong with the speed sensor. 

• Transmission difficulties.
• Inconsistent speedometer readings.
• Not being able to activate cruise control.
• Absence of torque converter clutch usage.
• The Check Engine Light comes on.

Now, let’s discuss these symptoms in detail.

Transmission difficulties.

Transmission slipping, grinding, or jumping when the vehicle is accelerating and changing gears. at any speed, a car will shake. You can smell burning under your hood. Visible fluid leakage from the car.

Inconsistent speedometer readings.

The signals from the wheel speed sensor are what most vehicles rely on to calibrate their speedometer readings.

Speedometer readings that are inconsistent or erratic can be the result of a bad speed sensor. It can also lead to completely blank readings.

Not being able to activate cruise control.

There are numerous fuses and relays that must all work properly in order for this to happen, and it is common for one of these fuses or relays to fail. 

The circuits required for the cruise control system to function can be broken by a blown fuse or faulty relay.

Check engine light.

When your “check engine” light illuminates, whether it is solid or blinking, it is best to have it repaired. 

The light could mean a lot of different things, and the majority of them will need to be identified and fixed by a mechanic. More often than you might imagine, your car’s performance is monitored by a computer.

How much does it cost to replace or repair the Harley speed sensor?

Vehicle speed sensor replacement typically costs between $282 and $326. While parts are priced between $164 and $178, labor costs are predicted to range between $117 and $148. 

Taxes and other fees are not included in this range, nor are your particular vehicle or geographic location taken into account. There might be additional repairs required.
