Terminals of ecuTransmission fluid temperature sensor "A" circuit
Description
The automatic transmission fluid (atf) temperature sensor converts the atf
temperature into a
resistance value which is input into the ecm.
The ecm applies a voltage to the temperature sensor through ecm terminal tho1.
The sensor resistance changes with the atf temperature. ...
Emission inspection

programs
Some states have vehicle emission inspection programs which
include obd (on board diagnostics) checks. The obd system
monitors the operation of the emission control system.

Can bus line
Description
When any dtc for the can communication system is output, first measure the
resistance between the
terminals of the dlc3 to specify the trouble area, and check that there is not a
short in the can main wire,
between the main wire, to +b, or to gnd.
