Differential Lock Hydraulic Fluid Temperature Sensor: Testing and Inspection

Coupling Air Temperature Sensor Inspection
Reference: Coupling Air Temperature Sensor Removal and Installation

CAUTION:
Do not heat up coupling air temperature sensor more than 100 °C (212 °F). Otherwise, coupling air temperature sensor will be damaged.

^ Blow hot air to temperature sensing part (2) of coupling air temperature sensor (3) using hot air drier (4) and measure resistance between sensor terminals while heating air gradually. If measured resistance does not show such characteristic as shown, replace air temperature sensor.
