Does the input speed sensor control the speedometer?
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. A faulty speed sensor can affect your speedometer operation and reduce your ability to drive safely.
How do you change the input speed sensor?
Replacing Your Transmission Speed Sensors
- Having found the sensor or sensors to be faulty, remove the connector between the sensor and the vehicle’s wiring.
- Using the proper socket, remove the faulty sensor.
- Connect the new sensor to the vehicle’s wiring.
- Install the new sensor.
- Lower your car.
- Start the engine.
What is output speed sensor?
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 input shaft speed sensor located?
The Input Shaft Speed Sensor is located on the 6-bolt PTO Cover, which is standard on the right side of the transmission. The sensor is a magnetic pickup that produces an AC voltage as the countershaft gear teeth moves past the end of the sensor. At idle the speed sensor output is low and increases as the speed of the countershaft increases.
How does the AC sensor work on an Eaton Fuller?
The sensor is a magnetic pickup that produces an AC voltage as the countershaft gear teeth moves past the end of the sensor. At idle the speed sensor output is low and increases as the speed of the countershaft increases. The following preconditions must be met before the system detects the fault:
How to check for an Eaton transmission error?
For all questions concerning inspection, removal, replacement, or adjustment procedures, refer to Eaton or OEM Service and Parts Literature. 1a. After activating the retrieval of codes, to read transmission errors via the Service Transmission light, observe the sequence of flashes exhibited by th e light.
What is the correct test sequence for Eaton Fuller automatic transmissions?
