What P2841 means
P2841 indicates that fork D reports a believable voltage but an implausible position. GM's 2023 table runs the rod 4 consistency test in the Corvette only when neither the even-clutch speed signal nor the output speed signal has shown an electrical fault for at least 100 ms, so the comparison has trustworthy speeds behind it. During engagement the sensor must reach the learned engaged point within 1100 µm once over 600 N push the rod; during release, a rod that stays within 1000 µm of its starting point counts against it. Type A, with a recovery attempt on the even shaft synchronizer. Ford's 2024 summary uses P2841 for TR9070 rod sensor 4 consistency and P277F for its drift, and Mercedes-Benz names it a fork D sensor malfunction on the 8G-DCT.
P2841 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyWorkshop only
- Typical labor1 to 10 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2841
- Hesitation or repeated attempts on even-gear shifts
- Gear not held, slipping back to neutral
- Warning lamp with reduced gear range
Common causes of P2841
- Most likelyRod 4 or its synchronizer sticking so the fork lags behind the command
- PossibleOutdated learned positions after a clutch or sensor replacement
- PossibleFork D sensor or magnet shifted in its mount
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2841 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8 | Area: transmission. |
| 41 | The exact fault in that area. |
What to do next
- Note P2841 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 P2841
What does P2841 mean?
P2841 means "Shift Fork D Position Circuit Range/Performance". P2841 indicates that fork D reports a believable voltage but an implausible position. It is a generic code, so it means the same on every make.
Is it safe to drive with P2841?
Drive gently and only to a workshop. With P2841 the car can go into limp mode (reduced power) to protect itself.
Will P2841 fail an emissions test?
Yes, it can. P2841 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 P2841 to fix?
Difficulty: workshop only. A typical repair takes 1 to 10 hours of work. This is a job for a workshop.
Will P2841 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
