P0822Gear Lever Y Position Sensor 1 Circuit

  • Generic OBD-II code · Powertrain
  • Can trigger limp mode
How the car detects it
Gear lever X and Y position sensors detect a selector's position in two directions: on an H-gate shift and select direction (a LuK patent uses two sensors about 90° apart), on a shift-by-wire lever its two axes. P0820 covers the whole X-Y circuit, P0821–P0824 and P082A–P082F sensor 1, P089A–P08A3 a redundant sensor 2. P0822 is the same for the Y axis – the second direction of movement, on an H-gate the select gate. No manufacturer document available to us uses it; GM reports the Y axis as P082D, P082E and P082F. A failed Y sensor can hide a gate change, for example into the manual gate or the reverse gate.
