CHECK "TRANSMISSION FLUID TEMPERATURE SENSOR"
1. Ignition "OFF".
2. Disconnect the "ATF 1 [C106-1] and ATF 2 [C106-2]" connector
3. Measure the resistance between terminal "9" of the "ATF 1 [C106-1]" harness connector and chassis ground.
A. Specification : Refer to "Reference data"









4. Is resistance within specifications?
YES
1) Go to "CHECK PCM/TCM" as below
NO
1) Check for open or short in harness. Repair as necessary and Go to "verification of vehicle repair" procedure
2) Replace "TRANSMISSION FLUID TEMPERATURE SENSOR 1" as necessary and Go to "verification of vehicle repair" procedure.
CHECK TCM
1. Ignition "ON" & Engine "OFF".
2. Disconnect the "ATF 1 [C106-1]" connector
3. Install scantool and select a SIMU-SCAN,
4. Simulate voltage (0 -> 5V) to "TRANSMISSION FLUID TEMPERATURE SENSOR 1, 2" signal circuit.




5. Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?
YES
1) Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as necessary and then go to "Verification of Vehicle Repair" procedure.
NO
1) Substitute with a known-good TCM and check for proper operation. If the problem is corrected, replace TCM as necessary and go to "Verification of Vehicle Repair" procedure.
