TROUBLESHOOTING <A/T>
AUTOMATIC TRANSMISSION (FF)
23A-19
DIAGNOSTIC TROUBLE CODE
PROCEDURES
Code No.15: A/T fluid temperature sensor system
OPERATION
•
The A/T fluid temperature sensor converts the
automatic fluid temperature to voltage, and send
the information to the engine-A/T-ECU.
•
The A/T fluid temperature rises, the resistance
decreases. Thus, the sensor output voltage
depends on the automatic fluid temperature. As
the A/T fluid temperature rises, the output voltage
will decrease.
diagnosis code set conditions
If the A/T fluid temperature sensor output voltage is
4.5 volts or more after driving for 10 minutes or more,
there is an open circuit in the A/T fluid temperature
sensor and diagnosis code 15 is set.
Possible causes
•
Malfunction of the A/T fluid temperature sensor
•
Damaged harness wires and connectors
•
Malfunction of the engine-A/T-ECU
