What P2E05 means
P2E05 flags implausible data from sensor B, the backup gear lever sensor. It is one of the few codes of this family with public manufacturer use. On 2022–24 Lexus NX 250/350 and 2022 NX 350h/450h+, Toyota stores it as P2E04-64, a plausibility failure of sensor B, often alongside P2E01; bulletin L-SB-0050-22 (revised October 2023) changes the floor shift assembly logic by reflash, with 0.8 h labour and no part swap. In GM's 2025 ECM tables (25OBDG04B) P2E05 belongs to gear lever position sensor 2: an internal error reported over the second SENT channel, threshold 99.84 %, 160 failures in 200 samples, blocked by lost-communication codes U1194, U1196, U13E1 and U13E3; Type B, two trips. Axis checks of that sensor are P089B and P08A0.

Symptoms of P2E05
- MIL on, usually without a driveability change
- Shift-system warning may appear and disappear
- Often stored together with P2E01
Common causes of P2E05
- Most likelyFloor shift assembly logic outdated (Lexus NX bulletin L-SB-0050-22)
- PossibleSensor B signals an internal error
- Less likelySensor B or its magnet misaligned after a repair in the console
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E05 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 05 | The exact fault in that area. |
What to do next
- Note P2E05 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 P2E05
What does P2E05 mean?
P2E05 means "Gear Lever Position Sensor B Range/Performance". P2E05 flags implausible data from sensor B, the backup gear lever sensor. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E05?
Drive gently and only to a workshop. With P2E05 the car can go into limp mode (reduced power) to protect itself.
Will P2E05 fail an emissions test?
P2E05 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 P2E05 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E05 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.
