What is an Automatic Transmission Revolution Sensor?
An Automatic Transmission Revolution Sensor (also known as a speed sensor) is a vital component of an automatic transmission system. It measures the rotational speed of the transmission's input shaft and sends an electrical signal to the Transmission Control Unit (TCU) so that it can make the necessary adjustments to shift gear ratios.
What is the purpose of an Automatic Transmission Revolution Sensor?
The purpose of an Automatic Transmission Revolution Sensor is to send an electrical signal to the Transmission Control Unit (TCU) that accurately reflects the rotational speed of the transmission's input shaft. This enables the TCU to make the necessary adjustments to shift gear ratios.
How do I know if my Automatic Transmission Revolution Sensor is faulty?
You may be able to detect a faulty Automatic Transmission Revolution Sensor if your vehicle is having difficulty shifting gears or staying in gear, or if the check engine light is illuminated. Additionally, if you have a scan tool, the transmission system may alert you to the fault.
Can a faulty Automatic Transmission Revolution Sensor cause damage to my vehicle?
Yes, a faulty Automatic Transmission Revolution Sensor can cause damage to your vehicle. If the sensor is malfunctioning, it can cause the transmission to shift erratically, which can result in damage to the transmission and other components.
How do I replace an Automatic Transmission Revolution Sensor?
1) Disconnect the negative terminal of the battery.
2) Locate the sensor. It is usually mounted on the transmission's tail shaft housing, in the rear of the engine.
3) Remove the electrical connector from the sensor.
4) Unscrew and remove the sensor from the tail shaft housing.
5) Install the new sensor and reconnect the electrical connector.
6) Reconnect the negative terminal of the battery.
How often should I inspect my Automatic Transmission Revolution Sensor?
It is recommended that you inspect your Automatic Transmission Revolution Sensor at least once a year. Regularly inspecting the sensor helps ensure that it is functioning properly, preventing potential damage to your vehicle.
