Component Inspection

  1. CHECK "TRANSAXLE FLUID TEMPERATURE SENSOR"
    1. Ignition "OFF".
    2. Disconnect the "TRANSAXLE FLUID TEMPERATURE SENSOR" connector.
    3. Measure the resistance between terminals "1" and "2" of the "TRANSMISSION FLUID TEMPERATURE SENSOR".

      Specification: Refer to ATF TEMPERATURE SENSOR RESISTANCE .

    4. Is resistance within specifications?

      YES 

      • Go to  2 as below.

      NO 

  2. CHECK TCM
    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 "TRANSMISSION 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 refer to VERIFICATION OF VEHICLE REPAIR .

      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 refer to VERIFICATION OF VEHICLE REPAIR .
