temperature sensor
circuit is open circuit.
3
Check transmission fluid temperature sensor circuit for
power supply short
1) Cool down A/T fluid temperature under ambient
temperature.
2) Connect TCM connectors to TCM with ignition switch
OFF.
3) Turn ignition switch ON.
4) Measure voltage between terminal “E92-11” of TCM
connector and ground.
Is it 4.89 V or more?

temperature sensor
circuit is shorted to
power supply circuit. If
circuit is OK, go to Step
4.
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to “Intermittent
and Poor Connection
Inspection in Section
00”. If OK, substitute a
known-good TCM and
recheck.
