April 5, 2026: LEMON Manuals is launched! Read the announcement.

Component Inspection

CHECK "TRANSAXLE FLUID TEMPERATURE SENSOR"

Ignition "OFF".
Disconnect the "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.

Measure the resistance between terminals "1" and "2" of the "TRANSAXLE FLUID TEMPERATURE SENSOR".

Specification: Refer to RESISTANCE SPECIFICATION CHART

RESISTANCE SPECIFICATION CHART

TEMP.[°C (°F)]	Resistance (kΩ)	TEMP.[°C (°F)]	Resistance (kΩ)
-40 (-40°F)	139.5	80 (176°F)	1.08
-20 (-4°F)	47.7	100 (212°F)	0.63
0 (32°F)	18.6	120 (248°F)	0.38
20 (68°F)	8.1	140 (284°F)	0.25
40 (104°F)	3.8	160 (320°F)	0.16
60 (140°F)	1.98

Is resistance within specifications?
YES : --> Go to 2 "CHECK PCM/TCM" as below.

no : --> Replace "TRANSAXLE FLUID TEMPERATURE SENSOR" as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.

CHECK PCM
1. Ignition "ON" & Engine "OFF".
2. Connect "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.
3. Install scan tool and select a SIMU-SCAN.
4. Simulate voltage (0 -->5V) to "TRANSAXLE FLUID TEMPERATURE SENSOR" signal circuit.

5. Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?
  YES : --> 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 : --> Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM as necessary and then go to "VERIFICATION OF VEHICLE REPAIR " procedure.
