Speedometer or Speed sensor has a very important role to play in the proper running of the vehicle. Speed sensor works on a very simple principle: there is a special socket that goes to either the output shaft of the transmission or the crankshaft of the engine. When the shaft rotates, the special socket attached to it also rotates. It is a sender device used for reading the speed of a vehicle’s wheel rotation. It usually consists of a toothed ring and pickup.
A faulty Speed sensor can be detected using a computer/ mobile device by connecting the computer/ mobile device to the vehicle using bluetooth.
Most Common Symptoms of a Faulty Engine Speed Sensor
A faulty vehicle speedometer sensor can cause a mix of problems. In fact, symptoms of a faulty speed sensor may also result in symptoms of other common components such as a defective coil pack or bad throttle position sensor. However, here is a list of the most common symptoms associated with a bad engine speed sensor:
- Transmission revs higher before it changes gears
- The truck’s transmission engages into overdrive later than required and sometimes will never go into the top gear
- Brakes are harder than normal
- Speedometer behaves inconsistently or does not work at all
- The check engine light comes on intermittently and intermittently when accelerating
- The overdrive on/off light blinks on and on for no reason
If your vehicle is experiencing any of the above problems, you should take your truck or vehicle into a local mechanic or garage or dealership to have them check through a computer diagnostic test on your vehicle.
