DTC detecting condition | Trouble area |
---|---|
Transmission temperature sensor terminal voltage is more than 4.6 V and shift range is in “R”, “D”, “2” or “L” for 15 minutes after starting engine. |
•
Transmission fluid temperature sensor or its circuit malfunction.
• TCM |
Step | Action | YES | NO |
---|---|---|---|
1 |
Was
A/T System Check
performed?
|
Go to Step 2.
|
Go to
A/T System Check
.
|
2 |
Check Transmission Fluid Temperature 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 “E121-11” and “E121-12” [A] or “E123-5” and “E123-14” [B].
4)
If OK, check continuity between terminals “E121-11” and “E121-12” [A] or “E123-5” and “E123-14” [B] of disconnected harness side TCM connector.
Is continuity indicated?
|
Go to Step 3.
|
“BLU/RED” or “GRN/RED” circuit open.
|
3 |
Check Transmission Fluid Temperature 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 “E121-11” [A] or “E123-5” [B] of TCM connector and ground.
Is it 4.6 V or more?
|
“BLU/RED” circuit shorted to power circuit.
If circuit is OK, go to Step 4.
|
Intermittent trouble or faulty TCM.
Check for intermittent referring to
Intermittent and Poor Connection Inspection
.
If OK, substitute a known-good TCM and recheck.
|
4 |
Inspect Transmission Fluid Temperature Sensor
Inspect transmission temperature sensor referring to
Transmission Fluid Temperature Sensor Inspection
.
Is result satisfactory?
|
Intermittent trouble or faulty TCM.
Check for intermittent referring to
Intermittent and Poor Connection Inspection
.
If OK, substitute a known-good TCM and recheck.
|
Replace transmission fluid temperature sensor.
