Code P0985 2010 Toyota Camry Description

The P0985 diagnostic trouble code (DTC) for a 2010 Toyota Camry indicates a problem with the Shift Solenoid 'E' Control Circuit Low Valve SR. This code is specifically related to the transmission system of the vehicle. The shift solenoid is responsible for controlling the flow of transmission fluid to engage or disengage specific gears within the transmission. In this case, the 'E' shift solenoid is experiencing a low voltage condition, which can lead to issues with shifting gears smoothly and efficiently.
