When to replace wheel speed sensors and why?
If the wiring is okay but the sensor is reading out of range, the sensor needs to be replaced. Note: On vehicles where the wheel speed sensor is an integral part of the hub and wheel bearing assembly, the entire hub must be replaced if the sensor is bad.
How do you replace a transmission speed sensor?
Step 2: Secure the wheels. Place wheel chocks around the tires that will remain on the ground. In this case, place the wheel chocks around the front tires since the rear of the vehicle will be lifted up. Engage the parking brake to the lock the rear tires from moving. Step 3: Install a nine volt battery saver into your cigarette lighter.
When to replace the speedometer in your car?
If you notice that the speedometer does not work any longer, replace the vehicle speed sensor as it is the most likely cause. It is important to make sure that you purchase the correct vehicle speed sensor for your car.
How does a speed sensor work on a car?
Some makes and models use a single sensor on a single wheel for the speed signal. Some vehicles that have anti-lock brakes use the wheel speed and the transmission output to determine any faults.
How much does it cost to replace a speed sensor?
The DIY cost for replacing a speed sensor is the cost of the 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 .
How much to replace a speed sensor?
Standard replacement parts cost about $68 for the front and about $97 for the rear. This would make replacing the front sensor cost about $221 with OE parts and about $128 with aftermarket parts. Replacing a rear speed sensor would be about $241 using OE parts and about $157 using aftermarket parts. Nov 5 2019
What does a bad speed sensor do?
A bad speed sensor most often affects the shifting of the automatic transmission. However, in cars with an onboard computer, the sensor also affects the ABS system , speedometer, cruise control and power steering. Proper diagnosis and repair is essential for safe operation of the car.
What are the symptoms of a bad transmission speed sensor?
Symptoms of a Bad or Failing Transmission Speed Sensor. Common signs include harsh or improper shifting, cruise control not working, and the Check Engine Light coming on. The transmission speed sensors are used to calculate the actual gear ratio of the transmission while in use.
How much does it cost to replace a transmission speed sensor?
Transmission speed sensors tend to cost around the same. Labor varies depending on the engine type, as some sensors are more accessible than others. If your mechanic needs to drop the transmission to replace a transmission sensor, you’re looking at bill around $800-1,000.
Where is the speed sensor on a car?
The vehicle speed sensor (VSS) is also commonly referred to as a transmission speed sensor or output shaft speed sensor. It is a small device—typically mounted somewhere on the transmission—that determines how fast your vehicle is going by measuring the rotation of a toothed wheel on a shaft inside the transmission.
What are the different types of transmission sensors?
There are two main types of transmission speed sensors: the input shaft speed sensor and output shaft speed sensor. An input shaft speed sensor measures the speed of the input shaft and torque converter, which matches the speed of the engine.

There are two types of speed sensors: transmission speed sensors and ABS speed sensors. There are two types of transmission speed sensors: the output shaft speed sensor and the input shaft speed sensor. Both types are commonly found in vehicles with automatic transmissions.
What happens if the speed sensor comes off?
If the magnet comes off the speed sensor, it will lodge itself into the transmission making a grinding noise. Depending on how the sensor failed, an engine light will illuminate to inform the driver that there is a problem. Step 1: Turn on the ignition and start the engine. Drive the vehicle around the block to see if the speedometer will operate.
