How long does a vehicle speed sensor last?
There’s no hard-and-fast rule to help you predict how long your wheel speed sensor is going to last. Unlike a brake light switch or brake caliper that can last as long as your vehicle, you can expect your transmission speed sensor to last between 30,000 and 50,000 miles.
How much is a transmission speed sensor?
Depending on the vehicle year, make and model, a speed sensor can cost as little as $7.92 or as much as $100. For most vehicles, the cost for a speed sensor is between $25 and $45. Follow these procedures for replacing a faulty vehicle speed sensor (VSS).
Can a bad speed sensor cause transmission problems?
The Vehicle Speed Sensor measures a vehicle’s speed. If it malfunctions or fails to work, then the automatic transmission may not operate as it should. This sensor may also cause the automatic transmission to go into failsafe mode – giving the appearance that the issue is more severe than it really is.
What is the name of the transmission speed sensor?
There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.
How does the wheel speed sensor work in a car?
Basically, this means that the wheel speed sensor tells the transmission control module what is happening in the car. The wheel speed sensor lets TCM properly adjust the shifting and gear changing accordingly. The wheel speed sensor also notifies the TPM of when to control and alter the function on the torque converter.
What happens if the VSS sensor is not working?
Vehicle speed information relayed by the VSS is used by the transmission control module (TCM) or powertrain control module (PCM) to determine shift timing. Therefore, a failing speed sensor will have a direct impact on automatic transmission operation.
