What P2595 means
P2595 is logged when the signal of turbocharger speed sensor B stays below the range the engine computer accepts, as with a short to ground or a sensor whose output has collapsed. Bentley names it for the W12 in Continental GT, GTC and Flying Spur from 2018 and later also in the Bentayga, stored in engine control unit 1 or 2. Unlike the plausibility code P2594, which may first be cleared and retested, the bulletin goes straight to the replacement of the affected sensor (G688 or G689) once wiring tests for opens and shorts pass; on the Bentayga the bank 1 sensor is much harder to reach. The opposite electrical fault is P2596, sensor A reports the same condition as P2580.
P2595 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 8 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2595
- Malfunction indicator lamp on
- Speed of the second turbo shown as zero or very low
- Possible reduction of boost
Common causes of P2595
- Most likelySpeed sensor B with collapsed output
- PossibleSignal wire of sensor B shorted to ground
- Less likelyCorroded or contaminated connector at sensor B
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2595 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 5 | Area: vehicle speed, idle control and auxiliary inputs. |
| 95 | The exact fault in that area. |
What to do next
- Note P2595 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 P2595
What does P2595 mean?
P2595 means "Turbocharger Speed Sensor B Circuit Low". P2595 is logged when the signal of turbocharger speed sensor B stays below the range the engine computer accepts, as with a short to ground or a sensor whose output has collapsed. It is a generic code, so it means the same on every make.
Is it safe to drive with P2595?
Drive gently and only to a workshop. With P2595 the car can go into limp mode (reduced power) to protect itself.
Will P2595 fail an emissions test?
Yes, it can. P2595 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2595 to fix?
Difficulty: hard. A typical repair takes 1 to 8 hours of work. This is a job for a workshop.
Will P2595 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
