Q: What does code P1795 mean?

CAN Bus Throttle Body Position. This code indicates that the engine control module (ECM) has detected a communication or plausibility fault on the controller area network (CAN) link that carries throttle body position data. The ECM expects a valid position signal from the throttle actuator control module over the CAN bus, and when that message is missing, corrupted, or disagrees with other throttle position inputs, it stores P1795 and typically illuminates the reduced power light.
