temperature sensor A at terminal “E92-11” and “E92-12”.
4) If OK, check continuity between terminal “E92-11” and
“E92-12” of disconnected harness side TCM connector.
Is continuity indicated?
Go to Step 3.
Transmission fluid
temperature sensor A
signal or ground, circuit
is open circuit. If circuit
is OK, go to Step 4.
3
Check transmission fluid temperature sensor A circuit
for IG 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?
“Transmission fluid
temperature sensor A
signal” circuit 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.
4
Inspection transmission fluid temperature sensor A
1) Inspection transmission fluid temperature sensor A
referring to “Transmission Fluid Temperature Sensor
Removal and Installation”.
Is check result satisfactory?
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.
Replace valve body

DTC P0741:
When driving vehicle with 4th or 5th gear in “D” range, difference
in revolution between engine and A/T input (input shaft speed) is
larger than specification although TCM commanded TCC
solenoid to turn ON.
(2 driving cycle detection logic)
• Mechanical malfunction of TCC solenoid valve.
• Malfunction of valve body assembly.
• Fluid passage clogged or leaking.
• Torque converter clutch malfunction.
DTC P0742:
When driving vehicle with 2nd, 3rd, 4th or 5th gear in “D” range,
