P2832 Shift Fork A Position Circuit Range/Performance

P2832 means the fork A position reading is electrically valid but disagrees with what the gearbox is doing. GM's 2023 table for the Corvette dual-clutch box runs this as a consistency check on rod 1: when clutch shaft and output speeds prove a gear is engaged with over 600 N applied, yet the sensor sits more than 1100 µm away from the learned engaged position, a Type A fault follows a confirmation time; a matching test watches disengagement. Ford's 2024 summary lists P2832 as the consistency code of rod position sensor 1 on the TR9070. Mercedes-Benz names it a malfunction of the fork A sensor on the 8G-DCT, and Ford's 2012 DPS6 summary uses it for a position error of shift drum A, including a blocked motor.

Likely causes

Sensor magnet or mounting shifted on the shift rod
Learned fork positions no longer valid after repair or wear
Shift rod, fork or drum binding mechanically

Symptoms

  • Gear on the odd shaft not engaged or dropped
  • Clunks or long pauses during shifts
  • Limp-home mode with warning lamp
