Does the TFT PID display 190 °-195 °C (374 °-383 °F) and the TFTV PID display 0 volts?
Yes | GO to B4 |

No | INSPECT and REPAIR the transmission vehicle harness signal return circuit for an open. If an open circuit is not found, INSTALL a new PCM, REFER to: Powertrain Control Module (PCM) . PROGRAM the PCM with the latest calibration level. PERFORM the Solenoid Body Strategy Data Download procedure. REFER to: Transmission Strategy Download . |

B4 CHECK TFT SENSOR RESISTANCE
Remove the transmission molded leadframe. REFER to: Shift Solenoids (SS) . Inspect for metal shavings on the exposed metal contacts or other components and clean the solenoid and transmission internal wiring harness frame terminals.
Measure the resistance between the transmission molded leadframe C1575-5 and C1575-6 , component side using the following chart:
C1575-5 | C1575-6 | |
°C | °F | Resistance |
-40 to -20 | -40 to -4 | 967K-284K |
-19 to -1 | -3 to 31 | 284K-100K |
0-20 | 32-68 | 100K-37K |
21-40 | 69-104 | 37K-16K |
41-70 | 105-158 | 16K-5K |
71-90 | 159-194 | 5K-2.7K |
91-110 | 195-230 | 2.7K-1.5K |
111-130 | 231-266 | 1.5K-0.8K |
131-150 | 267-302 | 0.8K-0.54K |
Does the temperature to resistance specification match?
Yes | To diagnose an overheating concern REFER to: Diagnosis By Symptom . |
