What does output shaft speed sensor do?
The output speed sensor measures how fast a vehicle moves and sends that information to other vehicle systems. The transmission control unit uses the speed to determine when to change gears, adjust the torque converter and display the vehicle’s speed in the speedometer.
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.
How does a Lexus vehicle speed sensor work?
After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the Engine Control Module ( ECM ). The ECM determines the vehicle speed based on the frequency of these pulse signals.
What should I do if my speed sensor is not working?
It may also turn your Check Engine light on intermittently when accelerating. If your Check Engine light is on, have the code scanned at a local O’Reilly Auto Parts to see if you need a new VSS. If it needs to be replaced, we can help you find the right replacement vehicle speed sensor for your car, truck, or SUV.
How does a taxi meter work in California?
Call 760-345-4347 or e-mail [email protected] ) 1) distance traveled in the “hired” (on) mode. The meter is connected to a device within the vehicle – normally a vehicle speed sensor or distance sensor today – which provides information on distance traveled via pulses corresponding to revolutions of the transmission, axle or transaxle.
Where is the speed sensor on the transmission shaft?
What Does a Speed Sensor Do? Most of the time, the VSS is located on the transmission output shaft. As such, the VSS may also be referred to as an output shaft speed sensor. Some vehicles use both an input and output shaft speed sensor to monitor transmission operation.
Which is the output shaft speed ( OSS ) sensor?
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.
Where does the data from the speed sensor go?
The data collected from this sensor is used by your vehicle’s speedometer and odometer. The transmission input shaft sensor (ISS) collects information on the rotational speed of the torque converter or the input shaft.
Is the VSS an input or output speed sensor?
As such, the VSS may also be referred to as an output shaft speed sensor. Some vehicles use both an input and output shaft speed sensor to monitor transmission operation.
