What P2750 means
P2750 says that sensor C produces pulses whose speed is implausible – it disagrees with what the engaged gear and the other shaft speeds predict, jumps too fast or carries noise. No manufacturer documents P2750 publicly. The published checks for neighbouring sensors show what such a test looks like: GM's 2023 dual-clutch TCM compares its clutch 2 sensor with engine speed when the clutch is locked and faults it at 150 rpm difference for 1.1 s, and Ford counts dropouts and noise spikes on sensor B and flags a gear mismatch after 2.5 s. A mechanical cause is just as possible as an electrical one: swarf on a magnetic sensor tip, a cracked reluctor, or slipping clutches that make the ratio comparison fail.
P2750 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor1 to 6 hours
- Clears after repairAfter a drive cycle
Symptoms of P2750
- Check engine light after driving
- Erratic shift points or flare between gears
Common causes of P2750
- Most likelyMetal particles on the sensor tip distorting the signal
- PossibleElectrical interference on the signal lead
- Less likelyInternal clutch slip making the speeds disagree
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2750 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. |
| 50 | The exact fault in that area. |
What to do next
- Note P2750 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 P2750
What does P2750 mean?
P2750 means "Intermediate Shaft Speed Sensor C Circuit Range/Performance". P2750 says that sensor C produces pulses whose speed is implausible – it disagrees with what the engaged gear and the other shaft speeds predict, jumps too fast or carries noise. It is a generic code, so it means the same on every make.
Is it safe to drive with P2750?
Drive gently and only to a workshop. With P2750 the car can go into limp mode (reduced power) to protect itself.
Will P2750 fail an emissions test?
Yes, it can. P2750 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 P2750 to fix?
Difficulty: hard. A typical repair takes 1 to 6 hours of work. This is a job for a workshop.
Will P2750 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.
