The speedometer is responsible for the display of vehicle’s real time speed, the speedometers are mostly electronic and the vehicle speed is measured with the help of speedometer sensors, this sensor is mostly located at the transmission which detects the drive’s rotational speed, the sensor basically delivers the pulses to vehicle ECU, which is then converted to numerical figure, that is displayed on the speedometer.
Pitzo Recommends:
The replacement of the speedometer sensor needs to be specific to the model and make of the vehicle, or it will result in inaccuracy, in case of any failure in the speedometer sensor the observations are clear unlike other complex sensors, so there is no need to have a proactive approach.
What symptoms indicate the replacement of the speedometer sensor?
- Non uniform speedometer readings
- Check engine light is on
- Cruise control failure.
How important is it?
Speedometer sensor measures speed of the driveshaft while rotating, this data is sent to the vehicle’s ECU and then it is converted into numerical data that is displayed on the speedometer, in case of this sensor failure, a user won’t be able to view the speed of the vehicle.
