Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle's battery to ensure safety.
Raise the vehicle securely on jack stands.

2. Remove the Input Speed Sensor

Locate the input speed sensor on the transmission.
Disconnect the electrical connector from the sensor.
Use a socket wrench to remove the sensor from its mounting location.
Tools Required: Socket set, ratchet, and extension.

3. Inspect and Clean

Inspect the mounting area for debris or metal shavings that could affect sensor operation. Clean the area if necessary.
Check the condition of the old sensor. If it appears damaged, it must be replaced.

4. Install New Input Speed Sensor

Place a small amount of transmission fluid on the O-ring of the new sensor to ensure a proper seal.
Install the new sensor into its housing, ensuring it is seated correctly.
Reconnect the electrical connector to the sensor.
Tools Required: Torque wrench (if applicable; refer to service manual for torque specifications).

5. Reconnect Battery and Test

Reconnect the vehicle's battery.
Start the engine and allow it to reach operating temperature.
Conduct a test drive to ensure proper operation of the transmission and check for error codes again.
