Speed Sensor

Before installing the Turbine Shaft Speed (TSS) Sensor determine whether its O-ring shows any damage; if it does replace it with new. Apply petroleum jelly to the O-ring before installation. The repair of TSS Sensor in 4x4 vehicles starts with removing the front driveshaft. When servicing the Turbine Shaft Speed (TSS) Sensor in 4x2 vehicles you need to place the vehicle in PARK position and hoist the vehicle. The service technician should follow the order of components removal indicated by both the illustration and table. The sensor installation requires performing the reverse procedure of removal steps.

Petroleum jelly serves as a preparatory step for installing the Turbine Shaft Speed (TSS) Sensor because you need to apply it to the sensor O-ring seal. 4x4 vehicle owners should remove the front driveshaft and 4x2 vehicle owners should place their vehcile on a hoist when it is in PARK position. Next remove the elements starting with the first sequence. The first step to remove the TSS sensor involves unscrewing its screw along with separating the sensor from the transmission system. Check the TSS sensor O-ring seal for damage before you proceed to replace it with an entirely new O-ring seal. Before fitting the TSS sensor inspectors should apply petroleum jelly to a new O-ring seal before installing it into the transmission and screwing it securely.

The service procedure for Output Shaft Speed (OSS) Sensor must start by placing the vehicle in NEUTRAL position on a hoist. The first step requires disconnecting the electrical connector while removing the OSS sensor. You should tighten the new sensor to 10 Nm (89 inch lbs) before performing the installation steps in reverse order.

The first step for servicing and repairing the Intermediate Shaft Speed Sensor requires petroleum jelly lubrication of its O-ring seal before final installation. The maintenance procedure for 4x4 vehicles requires removing the front driveshaft but 4x2 vehicles need to be placed on a hoist while in the PARK gear position. Then follow this sequence to remove all components. Start the intermediate shaft speed sensor removal process by unscrewing it before taking off the sensor from its transmission location. The O-ring seal requires examination for damage. If found damaged you should replace it with a fresh seal. Before putting the intermediate shaft speed sensor into place you must lubricate the O-ring seal with petroleum jelly then fasten the screw tightly.

The servicing process for the Output Shaft Speed (OSS) Sensor begins with oilying the sensor O-ring using petroleum jelly while checking for damage before replacing it with a new O-ring. The front driveshaft removal procedure can begin for servicing 4x4 vehicles. 4x2 vehicle service requires the vehicle to be in PARK mode while it rests on a hoist. Follow the sequence for taking out components that have been provided. The installation procedure requires executing the backward steps of removal.

Proceed to remove the components in the specified order as indicated in the accompanying illustration and table.

Position the vehicle on a hoist with it in NEUTRAL.

Disconnect the Output Shaft Speed (OSS) electrical connector.

The new sensor should be tightened to 10 Nm (89 inch lbs.).

Disconnect the OSS electrical connector.

Lubricate the sensor O-ring seal with petroleum jelly before installation.

Inspect the O-ring for any damage.

Begin by raising and supporting the vehicle.
