P2775Upshift Switch Circuit Range/Performance
- Generic OBD-II code · Powertrain
- How the car detects it
- P2775 covers an upshift paddle or tip switch whose voltage is electrically possible but belongs to neither of its two legal states. GM's twin-clutch TCM tables for 2023 and 2024 read the plus paddle as an analogue input: pressed should give 2.2–3.52 V, released 3.826–4.744 V. If the voltage sits outside both windows for 120 s, P2775 sets as Type C, so without MIL. Ford's 2024 summary for the TR9070 twin-clutch gearbox lists P2775 as illegal voltage on the upshift paddle input. Contact wear, moisture or a resistor drifting inside the switch are the usual reasons. A paddle held too long belongs to P0815, readings beyond the band to P2776 or P2777. Manual shifting by paddle is normally disabled.
