1992 BMW 325i Vehicle Speed Sensor Replacement Cost in Denver, CO

The vehicles that will experience the highest rate of failure for the vehicle speed sensor are those that are left unmaintained. As transmission fluid ages and becomes contaminated, those contaminates will become stuck to the speed sensor or ring, and prevent accurate readings. If the powertrain control module cannot read the vehicle speed, even though the sensor is working properly, the result will be the same as if the sensor had failed. Generally, a vehicle speed sensor should last well over 100,000 miles, and the average replacement frequency is closer to 150,000 miles, with exceptions. To prolong the life of your vehicle speed sensor, as well as all other components in your transmission, ensure you are maintaining the transmission in accordance with the owners manual service and maintenance section.

Diagnosing a failed speed sensor will begin with reading diagnostic trouble codes, checking the fuses for the circuit, and testing the circuit for presence and accuracy of battery voltage, signal voltage, and ground. If the circuit tests ok, there are a few safe ways to test the speed sensor, all of them involving a computerized diagnostic scan tool. It is not recommended to test the speed sensor. If the speed sensor is found to read incorrectly, a transmission flush may be recommended, but if the speed sensor is not functioning at all, it will need to be replaced.
