Component Inspection
WARNING: This page is about a different variant/trim than selected.
- CHECK "TRANSMISSION FLUID TEMPERATURE SENSOR"
- Ignition "OFF".
- Disconnect the "ATF 1 [C106-1] and ATF 2 [C106-2]" connector.
- Measure the resistance between terminal "9" of the "ATF 1 [C106-1]" harness connector and chassis ground.
Specification : Refer to RESISTANCE SPECIFICATION .
RESISTANCE SPECIFICATIONApplication PIN No TEMPERATURE (°F) RESISTANCE (KΩ) VOLTAGE (V) ATF 1 C106-1 : 9 - GND 32 Approx. 15 Approx. 3.3 68 Approx. 6.5 Approx. 2.7 176 Approx. 0.9 Approx. 0.9 ATF 2 C106-2 : 1 - GND 32 Approx. 10.5 Approx. 3.3 68 Approx. 4.3 Approx. 2.5 176 Approx. 0.5 Approx. 0.7 - Is resistance within specifications?
YES
- Go to "CHECK PCM/TCM " as below.
NO
- Check for open or short in harness. Repair as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure. Replace "TRANSMISSION FLUID TEMPERATURE SENSOR 1" as necessary and Go to "VERIFICATION OF VEHICLE REPAIR " procedure.
- CHECK TCM
- Ignition "ON" & Engine "OFF".
- Disconnect the "ATF 1 [C106-1]" connector.
- Install scan tool and access "SIMU-SCAN" mode.
- Simulate voltage (0→5V) to "TRANSMISSION FLUID TEMPERATURE SENSOR 1, 2" signal circuit.
- 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 TCM and check for proper operation. If the problem is corrected, replace TCM as necessary and go to "VERIFICATION OF VEHICLE REPAIR " procedure.
