4.13 DTC P0711 to P0713 – Transmission
Fluid Temperature Sensor
DTC Description
This diagnostic procedure supports the following DTCs:
• DTC P0711 – Transmission Fluid Temperature (TFT) Sensor Performance,
• DTC P0712 – Transmission Fluid Temperature (TFT) Sensor Circuit Low Voltage, and
• DTC P0713 – Transmission Fluid Temperature (TFT) Sensor Circuit High Voltage.
Circuit Description
The automatic transmission fluid temperature (TFT) sensor is part of the automatic transmission fluid pressure (TFP)
manual valve position switch. The automatic TFT sensor is a negative coefficient thermistor. The transmission control
module (TCM) supplies a 5 volt reference signal to the sensor and measures the voltage drop in the circuit. W hen the
transmission fluid is cold, the sensor resistance is high and the TCM detects high signal voltage. As the fluid temperature
increases, the resistance of the sensor decreases, which lowers the signal voltage. This diagnostic monitors the TFT
circuit. The circuit may be functional, but not in the normal operating range. This diagnostic indicates stuck, erratic,
intermittent, skewed, or inaccurate values, indicating poor system performance. The TFT range is -40 – 151°C.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
DTC P0711
• No DTC P0117, P0118, P0722 or P0723.
• DTC P0711 has not passed in the current ignition cycle.
• The engine run time is greater than 5 seconds.
• The transmission fluid temperature is -39 – 149°C.
• For conditions 1 and 2 in Conditions for Setting the DTC, the engine coolant temperature is greater than 70°C and
has changed by at least 50°C since start-up.
• For conditions 1 and 2 in Conditions for Setting the DTC, the TCC slip speed is 120 r.p.m. or greater for
600 seconds (10 minutes) cumulatively.
DTC P0712
The engine run time is greater than 5 seconds.

Action Taken When the DTC Sets
•
The TCM does not request the engine control module (ECM) to illuminate the MIL.
• The TCM records the operating conditions when the conditions for setting the DTC are met. The TCM records this
information as a Failure Record.
• The TCM stores DTC P0719 in TCM history.
Conditions for Clearing the DTC

4.15 DTC P0722 – Vehicle Speed Sensor
Circuit Low Voltage
DTC Description
This diagnostic procedure supports DTC P0722 Vehicle Speed Sensor Circuit Low Voltage.
Circuit Description
The vehicle speed sensor (VSS) provides vehicle speed information to the transmission control module (TCM). The VSS
is a permanent magnet generator. The sensor is mounted in the extension housing facing the rear internal gear which is
splined to the output shaft assembly. As the output shaft and internal gear rotate, the toothed rotor of the internal gear
produces AC voltage as the rotor teeth pass through the magnetic field of the sensor. The AC voltage level and the
number of pulses increase as the speed of the vehicle increases. The TCM converts the voltage to vehicle speed. The
TCM uses the output shaft speed signal to determine shift timing and torque converter clutch (TCC) scheduling.
If the TCM detects no vehicle speed when there is engine speed in a drive gear range, then DTC P0722 sets.
DTC P0722 is a type B DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
Conditions for Running the DTC
• No DTCs P0723, P1810, P1815 or P1816.
• Ignition voltage is 8 – 18 V.
• TFT is -40°C – 150°C.
• The engine run time is greater than 5 seconds.
• The throttle position is greater than 12 percent.
• The engine torque is 108 – 882 Nm.
Conditions for Setting the DTC
The transmission output shaft speed is less than 50 r.p.m. for 3 seconds.

4.18 DTC P0741 – Torque Converter Clutch
System – Stuck Off
DTC Description
This diagnostic procedure supports DTC P0741 Torque Converter Clutch (TCC) System - Stuck Off.
Circuit Description
The torque converter clutch (TCC) solenoid valve is a normally-open exhaust valve that is used with the torque converter
clutch pulse width modulation (TCC PWM) solenoid valve to control fluid acting on the converter clutch apply valve. The
TCC solenoid valve attaches to the transmission case assembly extending into the pump cover. W hen grounded by the
transmission control module (TCM), the TCC solenoid valve stops converter signal oil from exhausting. This causes
converter signal oil pressure to increase and move the converter clutch apply valve against spring force and into the
apply position. In this position, release fluid is open to an exhaust port and converter feed fluid fills the apply fluid circu it.
The converter feed fluid applies the TCC. When the TCM no longer provides a ground path, the TCC solenoid valve de-
energizes and apply fluid exhausts, releasing the TCC.
When the TCM detects high torque converter slip when the TCC is commanded off, then DTC P0741 sets. DTC P0741 is
a type B DTC.
Refer to 2 W iring Diagrams and Connector Chart to aid in diagnosis.
