- How the car detects it
- P2835 covers a fork A position signal that is present but unsteady. GM's 2023 Corvette dual-clutch table checks the carrier frequency of the rod 1 sensor and sets a Type A fault once it leaves the 1500 to 2500 Hz band for 150 ms; Ford's 2024 summary calls the same check on the TR9070 frequency out of range. In Ford's 2012 DPS6 summary for Fiesta and Focus the code has another meaning: the shift drum A motor reports its rotation through three Hall sensors, and P2835 sets when their pattern appears in the wrong order. Dropouts usually come from loose terminals, damaged shielding or interference on the signal wire. The driver may notice an occasional refused or delayed shift and a warning lamp that is not always on.
