1 vehicles · 1 makes
Most Reported On
P07A5 is an OBD-II diagnostic trouble code meaning “Transmission Friction Element "B" Stuck On.” This code sets when the transmission control module detects that friction element B (a clutch, band, or multi-disc pack) stays engaged when it was commanded to release. Because friction elements must apply and release in sequence to shift gears, one stuck on can tie up the transmission or cause harsh, incorrect shifts. Symptoms include harsh shifting, slipping, binding, or the transmission going into failsafe mode. This usually indicates an internal hydraulic or mechanical fault. This code is most commonly reported on 2022-2025 Nissan Pathfinder.
