What P2745 means
P2745 is the general circuit code for a second intermediate shaft speed sensor, called B. Such a sensor reads a shaft that turns between input and output, on a dual-clutch box typically the second clutch shaft. Ford's 2024 OBD summary documents it: its ten-speed automatics carry two intermediate sensors (the eight-speeds only one), and P2745 means sensor B has an open circuit or a short to ground, while a short to battery appears as P07C8. These hardware checks mature in roughly 1.5 s and run even when the car stands still. On Ford's TR9070 dual-clutch unit, the even-gear clutch shaft sensor is filed under the same P2745 family. Without the signal the module loses one ratio reference, so harsh shifts or a fixed limp-home gear are likely.

Symptoms of P2745
- Check engine light and transmission warning
- Harsh or delayed shifts
- Limp-home mode with a fixed gear
Common causes of P2745
- Most likelySignal or supply lead to sensor B broken or chafed to ground
- PossibleCorroded or loose pins at the transmission connector
- PossibleInternal fault of intermediate shaft speed sensor B
- Less likelyFaulty sensor input in the transmission control module
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2745 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. |
| 45 | The exact fault in that area. |
What to do next
- Note P2745 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 P2745
What does P2745 mean?
P2745 means "Intermediate Shaft Speed Sensor B Circuit". P2745 is the general circuit code for a second intermediate shaft speed sensor, called B. It is a generic code, so it means the same on every make.
Is it safe to drive with P2745?
Drive gently and only to a workshop. With P2745 the car can go into limp mode (reduced power) to protect itself.
Will P2745 fail an emissions test?
Yes, it can. P2745 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 P2745 to fix?
Difficulty: hard. A typical repair takes 0.5 to 6 hours of work. This is a job for a workshop.
Will P2745 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
