What happens when a vehicle speed sensor goes bad?

One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.

Where is the vehicle speed sensor located?

The vehicle speed sensor, or VSS, is located near the transmission’s output shaft. The specific placement of the sensor allows the sensor to detect, and report, to the engine’s computer through attachment cabling, the rotation and speed of the shaft.

Can you reset a speed sensor?

There are two of them, you may have changed the wrong one. INPUT speed sensor is closer to the motor than the OUTPUT speed sensor, which is closer to the driver side end of the trans case. You need the output one. You don’t need to reset anything but you can disconnect battery for say an hour if you want to do it.

How do I know if my speed sensor is working?

Connect the VSS to a power drill so you can simulate the rotation of the vehicle’s transmission and read the multimeter to see if the voltage increases as the speed increases to check if the sensor is working properly.

Can I drive with a bad speed sensor?

Can you drive with a bad speed sensor? In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car’s computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.

Will a bad speed sensor throw a code?

Its proper functioning depends on the data from the transmission speed sensors. If it fails to work, then it means the sensors have malfunctioned. The PCM will transmit an error code to ECU, which will shut down.

Can I drive my car with a bad speed sensor?

In general, it is unsafe to drive a vehicle with a broken wheel speed sensor. The car’s computer will not be able to determine the speed that your vehicle is traveling, so it might apply the brakes at a faster rate than necessary or increase the engine power.

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.

How can you tell if a speed sensor is bad?

Disconnect the sensor from the housing on the transmission, as indicated in the repair manual for your car. Disconnect the sensor’s wire coupling. Using the multimeter’s voltmeter connect the probes to the ground and reference wires in the connector. If no voltage is received, the sensor is faulty.

Will a speed sensor cause shifting problems?

When there’s no speed signal coming from the sensors, shifting of gears will be a problem because the powertrain control module won’t control them correctly. This will make the transmission not work properly. It will either shift more quickly or roughly than expected.

How much does it cost to get a speed sensor replaced?

To replace the speed sensor, you are going to pay, on average, between $330 and $380. The labor should only cost you between $80 and $100, while parts will run you about $265.
