DTC P1641: ACTTRQ Motor Torque Signal Circuit High Input: General Description

The engine control module (ECM) sends a request for motor torque to the motor control module (MCM). The MCM sends back the motor torque value as duty signals to the MCM. The duty signals are converted into voltage in the ECM and used for various controls. If the ACTTRQ motor torque signal voltage is a set value or more, a malfunction is detected and a DTC is stored.
