Toyota Sienna Service Manual: Actuator Supply Voltage Circuit / Open
DTC P0657 Actuator Supply Voltage Circuit / Open
DESCRIPTION
The ECM monitors the output voltage to the throttle actuator. This self-check ensures that the ECM is functioning properly. The output voltage is usually 0 V when the ignition switch is turned off. If the output voltage is higher than 7 volts when the ignition switch is turned off, the ECM will illuminate the MIL and set a DTC when the ignition switch is turned on.
