Pinpoint Test G : DTCS P0710, P0711, P0712, P0713, P1711, P1783
- G1 RETRIEVE AND RECORD ALL DTCS
- Using the diagnostic scan tool, retrieve all DTCs.
Are DTCs P0710, P0711, P0712, P0713, P1711 and/or P1783 present?
Yes For DTCs P0710, P0712 and/or P0713, GO to G2For DTCs P0711, P1711 and/or P1783, GO to G6 No REFER to: Diagnosis By Symptom - G2 CHECK THE TFT (TRANSMISSION FLUID TEMPERATURE) SENSOR SIGNAL INPUT
- Ignition OFF.
- Disconnect Transmission Vehicle Harness C1520A .
- Inspect the connector for damaged or pushed-out terminals, corrosion, loose wires and missing or damaged seals.
- Ignition ON.
- Enter the following diagnostic mode: TFT and TFTV.
Does the TFT PID display a temperature -39.9°F (-40°C) and the TFTV PID display 4.9 volts?
Yes GO to G5 No REPAIR the circuit. - G3 CHECK THE TFT (TRANSMISSION FLUID TEMPERATURE) SENSOR SIGNAL CIRCUIT
Does the TFT PID display a temperature 375.5°F (191°C) and the TFTV PID display 0.0 to 0.2 volts?
Yes GO to G5 No GO to G4 - G4 CHECK THE TFT (TRANSMISSION FLUID TEMPERATURE) SENSOR SIGNAL VOLTAGE
- Measure:
Positive Lead Measurement / Action Negative Lead C1520A-2 Ground
Is the voltage between 4.8 and 5.1 volts?
Yes GO to G5 No INSPECT and REPAIR the circuit. If an open circuit is not found, INSTALL a new PCM. REFER to: Powertrain Control Module (PCM) PERFORM the Transmission Strategy Download, REFER to: Transmission Strategy Download - Measure:
- G5 CHECK THE TFT (TRANSMISSION FLUID TEMPERATURE) SENSOR RESISTANCE
- Measure:
Positive Lead Measurement / Action Negative Lead Component side resistance pin 1. Component side resistance pin 2. Temperature

Does the temperature to resistance specifications match?
Yes To diagnosis an overheating concern, REFER to: Transmission Cooling No INSTALL a new transmission internal wiring harness frame. REFER to: Transmission Internal Wiring Harness Frame - Measure:
- G6 ON DEMAND SELF-TEST
- Check and make sure the transmission vehicle harness C1520A is fully seated, the terminals are engaged in the connector and in good condition before proceeding.
- Using the diagnostic scan tool, make sure the transmission fluid temperature is between 33.8°F (1°C) and 219.1°F (104°C).
- Perform the KOER self-test.
Is DTC P0711, P1711 and/or P1783 present?
Yes For DTCs P0711 and P1711, INSTALL a new transmission internal wiring harness frame. REFER to: Transmission Internal Wiring Harness Frame For DTC P1783, REFER to: Transmission Cooling No The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector. ADDRESS the root cause of any connector or terminal issue.
