To change the speed sensor on a 2005 Harley Fat Boy, first, ensure the bike is on a stable surface and disconnect the negative battery terminal. Locate the speed sensor on the transmission, usually near the rear of the bike. Remove the sensor's electrical connector and unscrew the mounting bolt to take out the old sensor. Install the new sensor in reverse order, reconnect the electrical connector, and reattach the battery terminal.
2007 for the FLSTF Fatboy had a 6 speed transmission
On a 2006 Harley Fat Boy, the speedometer sensor is typically located on the transmission. Specifically, it is mounted on the left side of the transmission case, near the rear. This sensor reads the rotation of the transmission gears to provide accurate speed readings to the speedometer. If you need to access or replace it, ensure the motorcycle is securely supported and consult the service manual for detailed instructions.

To change the speed sensor on a 2003 Harley Davidson Fat Boy, first, disconnect the negative battery cable to ensure safety. Locate the speed sensor on the transmission, typically near the primary cover, and remove the retaining bolt using a socket. Carefully pull out the old sensor, and install the new one by reversing the process, making sure to secure it with the bolt. Reconnect the battery and check for proper operation.
The speed sensor is mounted on the right side of the transmission case below the starter.
Speed Sensor is not working
Remove the wiring harness from your speed sensor. Remove the speed sensor retaining bolts. Reverse the process to install your new speed sensor.
which year model, what transmission do you have, and which speed sensor are we talking about?
A "speed" sensor can affect the shifting of the trans.A "speed" sensor can affect the shifting of the trans.
The vehicle speed sensor is powered and monitored by theECM. The ECM processes the vehicle speed signal andtransmits this signal to the TSMrrSSM/HFSM and speedometerthrough serial data.The vehicle speed sensor is located on the transmission justbehind the transmission top cover.
I'm not positive about this particular car, but on most cars the speed sensor screws into the transmission.
On a carbureted 88 Harley speed sensor, the red wire typically serves as the power supply, providing voltage to the sensor. The white wire usually acts as the signal output, transmitting the speed information to the speedometer or electronic control unit. The black wire is generally the ground, completing the circuit for the sensor's operation. Always refer to the specific service manual for your model for precise wiring details.
