DTC P1791 LINE PRESSURE SENSOR — Wiring Diagram — LPS —
AT-7108wiring diagramThe 'LPS' label notwithstanding, the schematic body is the standard four-solenoid pack diagram. The line pressure sensor itself is integrated inside the CVT assembly and the workshop manual doesn't draw it externally — the diagnostic is reduced to harness-continuity + CVT-assembly replacement.

NOTE
This page reuses the CVT solenoid-pack schematic as a context drawing. The actual line-pressure-sensor signal lands on TCM terminal 27 (B/R) per AT-7106 and is not drawn on this schematic.
