Hi and thanks for contacting YourMechanic. Check the throttle position sensor (TPS) for voltage and resistance. There should be a 5 volt reference voltage to the sensor with a ground. There should be a resistance on the sensor. If there is no resistance, then the TPS sensor needs replaced. If the sensor is good, then check the computer for voltage. If the computer is not showing any voltage, then the computer needs to be replaced for a bad connector. If you need further assistance troubleshooting the vehicle’s moving problem, then seek out a technician, such as one from YourMechanic, to assist with any needed repairs.
