The car on driving after warmup throws out a DTC code P0657 Powertrain error. Prior to the error message the car drives fine, accelerates and shifts fine. Automatic Transmission.
Upon receiving the error message P0657 the car goes into limp mode that allows me to get the car home. I understand the features of the safety mode but prior to this it had been acting fine. When I research the code further it indicates an "Actuator Supply Voltage Circuit/ Open. It reports the primary fix as "Repair Wire harness at Transmission."
Another fix listed on the report is "Repair Transmission Main Connector Wiring"
I can clear the code with my scanner, and it runs fine, no trouble with the transmission at all. Shifts fine, Goes into reverse fine. I cannot image that the transmission is bad.
Any thoughts on this would be appreciated.
