P2E01Gear Lever Position Sensor A Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- Here sensor A of the gear lever delivers values that are electrically valid but not believable. Two makers document the code. Lexus lists it as a signal plausibility failure (internal code P2E00-64) on 2022–24 NX models; bulletin L-SB-0050-22 cures it, together with P2E05, by reflashing the floor shift unit with revised logic, expressly without replacing it. GM's 2025 ECM tables (25OBDG04B) name it gear lever position sensor 1 performance: the sensor flags an internal error inside its SENT data, seen as alpha/beta at or above 99.84 %, in 160 of 200 samples and only while no communication fault is stored; Type B, MIL after two trips. GM checks the X and Y axes of the same sensor separately under P082A and P082D. Per GM's patent the partner sensor can take over.
- What you may notice
- MIL on after two trips
- Shift-system message, selector still works through sensor B
- Often no noticeable driving difference
- Likely causes
- LikelySelector logic needs a software update (Lexus NX 2022–24)
- PossibleSensor A reports an internal error
- RareMagnet or lever mechanism shifted, so sensor A reads off the gate
