What does code P1772 mean?

Q: What does code P1772 mean?

Load Signal Stuck On. P1772 on Volkswagen vehicles means the transmission control module (TCM) has detected that the load signal from the engine control module (ECM) is stuck at a constant value instead of fluctuating with engine load. The TCM expects this signal to change as throttle and engine demand vary, and a fixed signal prevents proper shift pressure and timing calculations.
