What P2862 means
P2862 indicates that a fork B actuator line sits at or near battery voltage when it should be pulled low. In practice this is a short to a powered conductor or a module transistor that stays open. Ford documents P2862 in its 2012 OBD summary as the short-to-power check of the DPS6 motor that turns the drum for reverse and gears 2, 4 and 6; the 2014 catalogue lists the MIL for it. Ford handles the open circuit as P285F and the ground short as P2861. Because the module cannot regulate the motor phases safely, it stops the motor and leaves that drum where it is; depending on where it stops, the box may be stuck without reverse or in one even gear. Inspect the harness routing near hot or moving parts before condemning the module.
P2862 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2862
- Engine lamp, no reverse or stuck in one even gear
- Large rpm jumps because only odd gears are used
Common causes of P2862
- Most likelyFork B actuator wire shorted to a powered conductor
- PossibleModule output transistor for fork B stuck
- Less likelyInsulation melted near the exhaust or a hot component
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2862 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. |
| 62 | The exact fault in that area. |
What to do next
- Note P2862 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 P2862
What does P2862 mean?
P2862 means "Shift Fork B Actuator Circuit High". P2862 indicates that a fork B actuator line sits at or near battery voltage when it should be pulled low. It is a generic code, so it means the same on every make.
Is it safe to drive with P2862?
Drive gently and only to a workshop. With P2862 the car can go into limp mode (reduced power) to protect itself.
Will P2862 fail an emissions test?
Yes, it can. P2862 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 P2862 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2862 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
