Located on the transmission case, within the rear differential assembly or inside the ABS system, the vehicle speed sensor reads the speed of the wheel rotation on a vehicle while driving.
Where is the speed control 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.
Where is the VSS speed sensor located?
VSS gives the onboard computer information about the vehicle speed. The sensor operates on the principle of the Hall Effect and is usually mounted on the tachometer or in the gearbox.
What are the symptoms of a speed sensor?
What Are The Symptoms Of A Faulty Speed Sensor?
- Inconsistent Speedometer Readings. Most cars depend on signals from the wheel speed sensor to adjust their speedometer readings. …
- The Check Engine Light Gets Activated. …
- Malfunctioning Cruise Control. …
- Harsh Transmission Shifting.
How do you remove a speed sensor?

Will a speed sensor cause shifting problems?
Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.
What is the difference between vehicle speed sensor and transmission speed sensor?
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.
How many transmission speed sensors are there?
A car has two speed sensors: the ISS and the OSS, working together to show the transmission data to the car’s powertrain module. The ISS sensor monitors the input shaft’s speed. If these sensors get misaligned, the operation of the transmission system will be affected.
How do you change a speed sensor?
DIY Auto Repair – Replacing a Vehicle Speed Sensor
- Disconnect the electrical connector and put that out of the way.
- Use a wrench or socket to remove the bolts. …
- Remove the sensor. …
- Coat the new VSS’ O-ring or seal with transmission fluid and reinstall.
How much does it cost to replace a speed sensor?
The average cost for vehicle speed sensor replacement is between $256 and $301. Labor costs are estimated between $107 and $135 while parts are priced between $149 and $166. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
What causes a speed sensor to go bad?
Over time, the transmission speed sensor can go bad due to wiring issues or just outright failing due to it constantly being used every time you are driving your vehicle. If the sensor is magnetic, it can go bad from iron sticking to the tip of the sensor, which will cause an inaccurate reading.
How can you tell if the 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.
Can a car run without a 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.
Where is traction control sensor?
Commonly located near the steering wheel on the instrument plane, you will be able to turn it back on via a simple switch. You should only feel the need to turn off the traction control in specific situations, usually involving being stuck in the likes of snow or mud.
Can you clean a transmission speed sensor?
Spray the brush with degreaser solution, and carefully remove any dirt from the reference ring. Thoroughly clean in between the holes and crevices of the reference ring, until it is free of debris.
Can you clean a wheel speed sensor?
With the sensor free, take your rag and wipe the sensor until it’s clean. I prefer not to use any chemicals on the sensor to avoid potential problems. If, however, the sensor is really grungy, use a mild soapy solution and rinse well. The ABS sensors are precision instruments in a crude environment.
Where is the transmission position sensor located?
The transmission position sensor is usually screwed onto the side of your car’s transmission. As you move the automatic gear selector from park/neutral to drive or reverse, it detects the changes.
Can speed sensor affect power steering?
Hello, the speed sensor can affect many things. The power steering, for example, needs to know how fast you are going to determine the amount of assist needed for steering.
How long does it take to replace a transmission sensor?
Three to four days. It usually takes three to four days to replace or repair the entire transmission system.
