P2782Downshift Switch Circuit Intermittent/Erratic
- Generic OBD-II code · Powertrain
- How the car detects it
- P2782 targets a downshift switch signal that flickers, bounces or vanishes for moments. No manufacturer documents P2782 publicly. The documented paddle monitors (GM's dual-clutch TCM tables of 2023/2024, Ford's TR9070 entry) cover low, high, implausible and held-too-long (P2779–P2781, P0816) without a separate dropout test, so such a fault there tends to surface under those codes. CARB's requirement to monitor transmission inputs for circuit and rationality faults is the basis for this code. A clock spring that loses contact only at certain steering angles is the classic cause, followed by a loose pin in the column connector and a minus paddle with a bouncing contact. The driver notices sporadic missed or unexpected downshifts that disappear again.
