What P2E01 means
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.
P2E01 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairAfter a drive cycle
Symptoms of P2E01
- MIL on after two trips
- Shift-system message, selector still works through sensor B
- Often no noticeable driving difference
Common causes of P2E01
- Most likelySelector logic needs a software update (Lexus NX 2022–24)
- PossibleSensor A reports an internal error
- Less likelyMagnet or lever mechanism shifted, so sensor A reads off the gate
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E01 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 01 | The exact fault in that area. |
What to do next
- Note P2E01 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E01
What does P2E01 mean?
P2E01 means "Gear Lever Position Sensor A Range/Performance". Here sensor A of the gear lever delivers values that are electrically valid but not believable. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E01?
Drive gently and only to a workshop. With P2E01 the car can go into limp mode (reduced power) to protect itself.
Will P2E01 fail an emissions test?
P2E01 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E01 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E01 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
