Transmission Oil Temperature Switch
Location
Description
Transmission Oil Temperature Switch is located in
the adapter on transmission (T/M) for operating by
the transmission (T/M) oil temperature change. This
switch is normally open, and then it is closed as the
T/M oil temperature Increases to the 125±3°C.
Actually if the switch is closed by high T/M oil
temperature, the ECM makes engine shutdown with
fault set. If the T/M oil temperature decreases to the
118°C, the switch is open again and the engine also
can run. This function can protect the engine of Tier-
3 and Non cert folk lift trucks from damage as
overheating.

Use an ohmmeter to check the continuity between
the 1 terminal and the 2 terminal. If there is
continuity, replace the Transmission Oil
Temperature Switch.
3.
The Transmission Oil Temperature Switch is the
‘ON/OFF’ switch. So during the normal status the
switch circuit should be open.
