5A-38 Automatic Transmission/Transaxle:
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check transmission fluid temperature sensor circuit for
open
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmission fluid
temperature sensor at terminals "G08-5" and "G08-14".
4) If OK, check continuity between terminals "G08-5" and
"G08-14" of disconnected harness side TCM connector.
Is continuity indicated?
3 Check transmission fluid temperature sensor circuit for
ground short
1) Turn ignition switch OFF.
2) Disconnect TCM connectors from TCM.
3) Check for proper connection to transmission fluid
temperature sensor at terminals "G08-5" and "G08-14".
4) If OK, check continuity between terminals "G08-5" of
disconnected harness side TCM connector and ground.
Is continuity indicated?
4 Check transmission fluid temperature sensor 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 "G08-5" of TCM
connector and ground.
Is it 4.6 V or more?
5 Inspect transmission fluid temperature sensor
1) Inspect transmission temperature sensor referring to
"Transmission Fluid Temperature Sensor Inspection".
Is result satisfactory?
Action Yes
Go to Step 2.
Go to step 3.
"BLU/ORN" circuit
shorted to ground.
"BLU/ORN" circuit
shorted to power circuit.
If circuit is OK, go to
Step 5.
Intermittent trouble or
faulty TCM. Check for
intermittent referring to
"Intermittent and Poor
Connection Inspection
in Section 00 in related
manual". If OK,
substitute a known-
good TCM and recheck.
No
Go to "A/T System
Check".
"BLU/ORN" or "LT GRN"
circuit open.
Go to Step 4.
Intermittent trouble or
faulty TCM. Check for
intermittent referring to
"Intermittent and Poor
Connection Inspection
in Section 00 in related
manual". If OK,
substitute a known-
good TCM and recheck.
Replace transmission
fluid temperature
sensor.
