Basic inspection

When measuring resistance of electronic parts Unless otherwise stated, all resistance measurements should be made at an ambient temperature of 20°c (68°f). Resistance measurements m ...

Other materials:

Transmission 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. ...

Shift solenoid "d" control circuit
Description Shifting from 1st to o/d is performed in combination with the on and off operation of the shift solenoid valves sl1 and sl2, which are controlled by the ecm. If an open or short circuit occurs in any of the shift solenoid valves, the ecm controls the remaining normal shift sol ...

Cold start
Description The electronic throttle control system (etcs) controls the engine idling speed. The etcs operates the throttle actuator to open and close the throttle valve, and adjusts the intake air amount to achieve the target idling speed. In addition, the ecm retards the ignition timi ...
