5. CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR A SHORT TO VOLTAGE Turn the ignition off to the lock position. Disconnect the TCM C2 harness connector. Ignition on, engine not running Measure the voltage of the (T52) Output Speed Sensor Signal circuit. Is the voltage above 0.2 volts? Yes >> Repair the (T52) Output Speed Sensor Signal circuit for a short to voltage. Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS- No >> Using the schematics as a guide, check the Transmission Control Module (TCM) terminals for corrosion, damage, or Perform CVT VERIFICATION TEST. (Refer to 21 - TRANS- 6. CHECK THE (T52) OUTPUT SPEED SENSOR SIGNAL CIRCUIT FOR AN OPEN (HIGH RESISTANCE) Turn the ignition off to the lock position. Disconnect the TCM C2 harness connector. Connect a jumper wire between the (T52) Output Speed Sensor Signal Using a 12-volt test light connected to ground, check the (T52) Output NOTE: The test light must illuminate brightly. Compare the bright- Does the test light illuminate brightly? Yes >> Go To 7 No >> Repair the (T52) Output Speed Sensor Signal circuit for an open or high resistance. Perform CVT VERIFICATION TEST.
