P2E0B: sensor C of the gear lever reports more than its maximum valid signal. That is the typical picture of a broken signal wire on a pulled-up input, contact with the feed line or a lost sensor ground. No manufacturer documents P2E0B, and the function of a third lever sensor is nowhere specified publicly. Toyota's patent US10180184 shows why a selector might carry one: with four Hall sensors one can drop out while three still define the lever position; only if another abnormality follows does the patent foresee a fail-safe such as a shift to neutral. On GM's two-sensor lever, duty cycles above 95 % raise the per-axis codes P082C and P089D. Low is P2E0A. CARB 1968.2 (e)(15) requires two-sided range checks on such inputs.

Likely causes

Signal wire of sensor C open
Ground of sensor C interrupted
Signal wire shorted to supply voltage

Symptoms

  • Warning lamp or shift message
  • Selector keeps working with the other sensors
  • Neutral forced if another sensor also fails
