What does the input turbine speed sensor do?
A turbine speed sensor, also termed an input speed sensor, is used for measuring the performance of the turbine by evaluating transmission performance and other components of the turbine. It also detects the rotation speed of the turbine, which shows the input revolution of the transaxle.
Can a speed sensor stop a car from moving?
This is because the system requires the sensor’s data in order to keep your car running at a constant speed. A bad speed sensor may automatically disable your vehicle’s cruise control.
What can a bad transmission speed sensor cause?
Harsh or improper shifting 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.
Where is the input turbine speed sensor?
Located on or inside your vehicle’s transmission, the turbine speed sensor measures the RPM of the turbine shaft. Once the PCM or TCM detects an irregularity in the turbine speed input, it will trigger the illumination of the Check Engine Light.
What happens when a cruise control sensor fails?
When the sensors fail to deliver accurate data to the onboard computer on your car, truck, or SUV, the powertrain control module (PCM) will send an error code to the vehicle’s ECU. As a safety precaution, the ECU will shut down the cruise control and render it inactive.
Why is my turbine speed sensor no signal?
If it doesn’t get that signal, the computer sets a P0717 Input Turbine Speed Sensor Circuit No Signal. Either the sensor is dead or there’s a circuit issue (bad wiring, etc).
How does the VSS work on a Toyota Land Cruiser?
The VSS is one part of a system of sensors that helps keep you safe (traction control, ABS, cruise control). A modern vehicle’s speedometer takes the input from the Vehicle Speed Sensor and sends that data to the ECU. The ECU is programmed with your Land Cruiser’s gear ratios and stock tire height.
How does a bad speed sensor affect your car?
A failing speed sensor can affect more than just speedometer operation. The engine and transmission control systems both rely on the data provided by the VSS to make the necessary adjustments for your vehicle to run efficiently. Depending on the vehicle, other systems (such as cruise control) may rely on this data as well.
