P1794-SPEED SENSOR GROUND ERROR (CONTINUED) 4. (T13) SPEED SENSOR GROUND CIRCUIT SHORT TO GROUND Measure the resistance between ground and the (T13) Speed Sensor Is the resistance below 5.0 ohms? Yes >> Repair the (T13) Speed Sensor Ground circuit for a short to ground. Perform 45RFE/545RFE TRANSMISSION VERIFICATION No >> Go To 5 5. (T13) SPEED SENSOR GROUND CIRCUIT SHORT TO VOLTAGE Ignition on, engine not running. Measure the voltage of the (T13) Speed Sensor Ground circuit. Is the voltage above 0.5 volt? Yes >> Repair the (T13) Speed Sensor Ground circuit for a short to voltage. Perform 45RFE/545RFE TRANSMISSION VERIFICATION No >> Using the schematics as a guide, check the Powertrain Control Module (PCM) terminals for corrosion, damage, or Perform 45RFE/545RFE TRANSMISSION VERIFICATION 21 - 274 AUTOMATIC TRANSMISSION 545RFE - ELECTRICAL DIAGNOSTICS WK |
