P2862Shift Fork B Actuator Circuit High
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- How the car detects it
- 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.
- What you may notice
- Engine lamp, no reverse or stuck in one even gear
- Large rpm jumps because only odd gears are used
- Likely causes
- LikelyFork B actuator wire shorted to a powered conductor
- PossibleModule output transistor for fork B stuck
- RareInsulation melted near the exhaust or a hot component
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
