P2E00Gear Lever Position Sensor A Circuit
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- How the car detects it
- Gear lever position sensor A is the first of up to four sensors through which an electronic selector tells its control module where the lever sits. In the designs GM and Toyota document, A and B form a redundant pair that each report the full lever position; GM's patent US9249877 has each of its two sensors deliver an x and a y value. P2E00 is the umbrella circuit fault of sensor A: an open line, a lost supply or a signal the module cannot evaluate, without splitting it into low or high. No manufacturer documents P2E00 publicly; in its 2025 ECM tables GM lists only P2E01 for this sensor and suspends that test while lost-communication U codes are stored. CARB 1968.2 (e)(15) requires circuit monitoring of such transmission inputs. With sensor B valid, shifting usually continues.
- What you may notice
- Warning lamp or shift-system message

- With a second fault, the vehicle may stay in P or N
- Likely causes
- LikelyLoose connector or chafed wire at the selector assembly
- PossibleSupply or ground of sensor A interrupted
- PossibleSensor A inside the selector assembly failed
- RareInput stage of the evaluating module faulty
