Q: What does code P1711 mean?

Engine Torque Control Signal 1 Circuit Malfunction. P1711 on a Subaru indicates that the engine control module (ECM) has detected an abnormal signal on the torque control signal 1 circuit, which is used to coordinate engine torque output with the transmission control module (TCM) during gear shifts. The ECM monitors the expected voltage or data from the torque control signal circuit and sets this code when the signal is out of range, missing, or implausible for a calibrated period.
