TRANSMISSION FLUID TEMPERATURE (TFT)
SENSOR (AIT ONLY)
If the transmission fluid temperature sensor circuit has
an open or short, Diagnostic Trouble Code No. P0712,
PO71 3, or P I 71 1 is output.
If the transmission fluid temperature sensor is open or
shorted, erratic shifting may be felt.
lnspection
1. Access TFT PID on SST (NGS tester).
2. Monitor the TFT PID voltage as the engine warms to
normal operating temperature.
Specification:
3. If TFT PID does not increase as engine reaches normal
operating temperature, inspect TFT sensor resistance
with SST (AT Tester: 49-UN01-071). Refer to Section K.

TURBINE SHAFT SPEED (TSS) SENSOR (M ONLY)
If the turbine shaft speed sensor has an open or short, Diagnostic Trouble Code No. PO71 5 is output.
If the turbine shaft speed sensor circuit is open or shorted, no symptom will be noticed.

connector.
4. Measure the resistance between the terminals of the TSS
sensor.
Resistance: 64-200 ohms
