The P1745 code is an informational code that alerts the technician about the transmission operating in an open-loop line pressure control for a significant distance or a large number of 2-3 upshifts. This condition is caused by a Line Pressure Diagnostic Trouble Code (DTC).

It’s important to note that the transmission is not designed to operate in open-loop line pressure control for an extended period of time. The purpose of this code is to protect the transmission.

When the P1745 code is detected, the transmission controller will activate limp-in mode as a precautionary measure.

In summary, the P1745 code indicates that the line pressure has been too high for an extended duration.
