2. CHECK THE (T54) TRANSMISSION TEMPERATURE SENSOR SIGNAL CIRCUIT FOR A SHORT TO Turn the ignition off to the lock position. Disconnect the TCM C2 harness connector. Disconnect the Transmission Solenoid/Pressure Switch Assembly har- Measure the resistance between ground and the (T54) Transmission Is the resistance below 5.0 ohms? Yes >> Repair the (T54) Transmission Temperature Sensor Signal circuit for a short to ground. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS- No >> Go To 3 3. CHECK THE (T54) TRANSMISSION TEMPERATURE SENSOR Temperature Sensor Resistive Values Chart Transmission Temperature Resistive Value Compared to Temperature (± 10%) 20° C (68° F) 2.5k ohms to 6.5k ohms 80° C (176° F) 0.3k ohms to 0.9k ohms Reconnect all previously disconnected connectors. Start the engine and allow to obtain normal operating temperature Turn the ignition off to the lock position. Disconnect the TCM C2 harness connector. Measure the resistance between the (T54) Transmission Temperature Is the resistance within the desired range listed on the above Yes >> Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or PM AUTOMATIC - CVT-ELECTRICAL DIAGNOSTICS 21 - 147 |
