System descriptionTransmission 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. ...
   
Deterioration of battery
   Description
The ecm determines the battery power according to the voltage of the batt 
terminal while the engine is
running (not cranking).
Inspection procedure
	Inspect battery
	Inspect the battery specific gravity.
	Check the specific gravity of each cell.
Standard gravity: ...
