P0953Auto Shift Manual Control Circuit High
- Generic OBD-II code · Powertrain
- How the car detects it
- Voltage on the manual up/down request circuit lies above its expected window. Common reasons are a signal wire shorted to battery voltage or, where the input is pulled up internally, a broken wire or a switch that never closes. A Volkswagen patent names a short to plus and a line break as faults its tip-gate diagnosis detects with the lever in P or R; a Chrysler patent shows the classic AutoStick-style gate with one switch for up and one for down. No manufacturer documents this exact code publicly; CARB requires circuit checks on such inputs. P0952 covers the low side, P0954 dropouts, P0950 the general fault. Manual shifting is usually disabled, automatic mode remains.
