Ignition "OFF".
Disconnect the "TRANSAXLE FLUID TEMPERATURE SENSOR" connector
Measure the resistance between terminals "5" and "6" of the "TRANSAXLE FLUID TEMPERATURE SENSOR".
Specification : Refer to " Reference data"
TEMP.(℉) | RESISTANCE(kΩ) | TEMP.(℉) | RESISTANCE(kΩ) |
-40(-40℉) | 139.5 | 80(176℉) | 1.08 |
-20(-4℉) | 47.7 | 100(212℉) | 0.63 |
0(32℉) | 18.6 | 120(248℉) | 0.38 |
20(68℉) | 8.1 | 140(284℉) | 0.25 |
40(104℉) | 3.8 | 160(320℉) | 0.16 |
60(140℉) | 1.98 | ||
Is resistance within specifications?
 | ▶ Go to "CHECK PCM/TCM " as below. |
 | ▶ Replace "TRANSAXLE FLUID TEMPERATURE SENSOR" as necessary and Go to "Verification Vehicle Repair" procedure. |
Ignition "ON" & Engine "OFF".
Connect "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.
Install scantool and slect a SIMU-SCAN,
Simulate voltage (0→5V) to "TRANSMISSION FLUID TEMPERATURE SENSOR" signal circuit.
Fig 1) INPUT 1.00V → 70℃
Fig 1) INPUT 2.00V → 40℃
※ The values are subject to change according to vehicle model or conditions.
Is FLUID TEMP. SENSOR signal value changed according to simulation voltage?
| ▶ 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. |
| ▶ Substitute with a known-good PCM/TCM and check for proper operation. If the problem is corrected, replace PCM/TCM and then go to "Verification of Vehicle Repair" procedure. |
