What P2765 means
P2765 is the circuit code of a second input speed sensor, B, and what B measures varies. On Ford's DPS6 dual-clutch box (2012) it is the input shaft 2 sensor for reverse and the even gears, faulted when the TCM hardware detects a circuit failure. Audi bulletin 2032211/3 for the 0B5 S tronic (S4/S5 2010–14, RS5/S6/S7 2013–14) lists P2765 among codes caused by a faulty sensor module G676 carrying the input speed sensors; it is replaced with its harness, which means removing the gearbox. Nissan's NTB14-019 (2014 Rogue, CVT8) ties P2765 to moisture on the pins of the secondary speed sensor. Mitsubishi's 2019 CVT uses it for the turbine sensor: under 150 rpm for 5 s with the primary pulley above 500 rpm.

Symptoms of P2765
- Check engine light and gearbox malfunction message
- Limp-home mode, sometimes without reverse or even gears
- Slow take-off and no torque converter lock-up
Common causes of P2765
- Most likelyMoisture or corrosion at the sensor B connector pins
- PossibleDefective sensor B or integrated sensor module inside the gearbox
- PossibleOpen or shorted wiring between sensor and TCM
- Less likelyTCM input stage faulty
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2765 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 65 | The exact fault in that area. |
What to do next
- Note P2765 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 P2765
What does P2765 mean?
P2765 means "Input/Turbine Shaft Speed Sensor B Circuit". P2765 is the circuit code of a second input speed sensor, B, and what B measures varies. It is a generic code, so it means the same on every make.
Is it safe to drive with P2765?
Drive gently and only to a workshop. With P2765 the car can go into limp mode (reduced power) to protect itself.
Will P2765 fail an emissions test?
Yes, it can. P2765 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 P2765 to fix?
Difficulty: hard. A typical repair takes 0.5 to 10 hours of work. This is a job for a workshop.
Will P2765 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
