P0841 — Transmission fluid pressure sensor/switch A — range/performance
Reference detail for fault code P0841 on the 0DR transmission.
What P0841 indicates
The 0DR transmission control unit stores P0841 when it detects the following condition: Transmission fluid pressure sensor/switch A — range/performance. The fault concerns a pressure sensor or pressure switch in the transmission. The control unit uses these signals for clutch and system pressure control, and stores the code when the signal is out of range, too low or implausible. A stored code does not by itself prove that a part has failed. Before replacing anything, check the live data, wiring, connectors, power supply and fluid condition, and confirm the fault on the vehicle.
