Jotting down the technical terminology of speed sensors, the part has a very vital significance in the overall working of the vehicle. A speed sensor in a vehicle generates a steady magnetic pulse in the pattern similar to a wave which is directly proportional to the speed of the vehicle. In simpler terms, if the vehicle is moving at a high speed it will generate high-frequency waves which will be proportional to the speed of the vehicle. The Electronic Control Unit of an Anti-lock Braking System (ABS) deals directly with the speed sensors and receives information regarding various electrical mechanisms such as fuel injection, ignition, cruise control, torque, and wheels lock-up. Replacing a vehicle speed sensor isn’t a very difficult task; you just need few tools and a step-by-step guide to get through the whole process. A vehicle speed sensors are externally-mounted and positioned on the transmission, secured in place by one or two bolts. Things you’ll need

• Open-ended wrench
• Jack Stand
• Socket extension
• Directional light
• New speed sensor shaft
• New vehicle speed sensor
• Engine lubricant

Steps to replace vehicle Speed Sensors Step 1: First, park the car in a safe spot and turn the engine off. Step 2: Let the engine cool off before getting down to the business. Step 3: Using the jack kit, jack up the front part of your car until there is sufficient space for you to crawl underneath the car. Step 4: Now, lying on your back, look up and start looking for the speed sensor. It is located on the bottom of the transmission. It is a small plug that is jutting out of the transmission. You’ll see an electrical connector attachedto it. Step 5: The electrical connector will have a release tab, just squeeze it to remove the connector from the sensor. Step 6: Now, using the open-ended wrench, pull the speed sensor in-between it and twist it counterclockwise, until the speed sensor is loose enough to pull out from the transmission. Step 7: Now, put the new speed sensor in place and instead of revolving it counterclockwise, twist it clockwise to secure it in place. Step 8: Again, plug the electrical connector on the sensor, see if everything is done and slide out from under the car.
