What Is The VSS Sensor?

A wheel speed sensor or vehicle speed sensor (VSS) is a type of tachometer. 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.


Can you drive with a broken speed sensor? That is why in general, it is unsafe to drive a vehicle with a broken wheel speed sensor. If the wheel speed sensor becomes damaged or wears out, initially you probably won't notice much difference in the way your car performs if your ABS light comes on unless you are driving on slippery pavement.

how does a VSS sensor work?

Basic Functionality of the VSS The top of the VSS senses the output of the transmission. Its opposite side is connected to a rotating magnet, which generates a voltage. This voltage is then transmitted to a computational device that calculates the speed proportional to the moving vehicle.

How do you fix a speed sensor? How to Repair a Vehicle Speed Sensor Park the vehicle on a level surface. Engage the emergency brake and turn the engine off. Place a vehicle jack on the left side and right side of the automobile. Look straight up on the passenger side of the vehicle. Unplug the electrical wire. Align the replacement speed sensor into the transmission.

where is the VSS sensor located?

The Vehicle Speed Sensor (VSS) is located on the right side of the transmission near the output shaft.

Can a speed sensor be cleaned? The various components of the speed sensors can gather dirt from the road and from the dust that is generated by constant sharp braking. Speed sensors need to be cleaned on a regular basis to avoid damaging the anti-lock braking system.

what happens when a speed sensor goes bad?

When there are symptoms of a bad transmission speed sensor, the powertrain control module cannot control the shifting of gears within the transmission properly. This may cause transmission revs higher before shifting gear or leading late transmission overdrive and inability to go into that top gear.

How many speed sensors does a car have? There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle's powertrain control module.

How do you test a VSS speed sensor?

Vehicle Speed Sensor Testing

What sensor controls the speedometer? A vehicle speed sensor (VSS), also known as an output speed sensor (OSS), is what tells your vehicle's control unit how fast the vehicle is going. Your vehicle's speedometer and odometer rely on the information from this sensor.

How do I know if my speed sensor is bad?

Most Common Symptoms of a Faulty Engine Speed Sensor Transmission revs higher before it changes gears. The car's transmission engages into overdrive late and sometimes will never go into that top gear. Brakes are sometimes harder than normal when coasting. Speedometer behaves erratically or sometimes does not work at all.

How much is a 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).

What does a speed sensor?

Transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use. There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle's powertrain control module. The other sensor is the output shaft speed (OSS) sensor.

How do sensors work?

Basically there are two types of sensors: active and passive. The sensor working principle in each of these devices varies to a certain extent. These sensors use ultrasonic sound waves to track any movement in the specified range. The detectors emit ultrasonic sound waves and wait for the energy to be reflected back.

Can a speed sensor cause shifting problems?

Even in a manual vehicle, a bad transmission speed sensor can cause gear shifting problems. Just moving the stick can be more difficult, and you may notice that the shaft feels rougher, or faster than usual when you shift.

Can a sensor cause transmission problems?

Manifold Airflow Sensor If it fails it can cause automatic transmission problems such as late harsh shifts, early soft shifts, or can result in no shifting at all. The mass airflow sensor is directly related to engine performance, so an issue may affect the drivability of the vehicle and a poor running engine.

How much does it cost to replace a transmission sensor?

The average cost for a transmission position sensor replacement is between $234 and $318. Labor costs are estimated between $121 and $154 while parts are priced between $113 and $164. Estimate does not include taxes and fees.

How much does it cost to fix a wheel speed sensor?

The average cost for a wheel speed sensor replacement is between $200 and $298. Labor costs are estimated between $63 and $80 while parts are priced between $137 and $218. Estimate does not include taxes and fees.
