P2E16Intermediate Shaft Selection Actuator Position Sensor Range/Performance
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- P2E16 flags a position reading from the intermediate shaft selection actuator that is electrically valid but not credible, for example a travel that does not match the commanded movement or the learned end stops. No manufacturer documents P2E16 publicly. Why learned references matter is explained in Ford's DPS6 dual-clutch summary from 2012: its clutch actuators sense motor position with Hall elements that only count steps, so the system must sweep from one end stop to the other to know the absolute position. If counts are lost or the mechanism no longer reaches its stops, the computed position drifts away from reality. GM judges plausibility of a rod sensor against shaft speeds (P2832 in 23OBDG07). A relearn after battery work or repair may clear the fault; otherwise check the mechanism.
- What you may notice
- Harsh, slow or failed shifts involving the intermediate shaft
- Transmission warning, possibly limp mode
- Fault returns until a relearn has been done
- Likely causes
- LikelyEnd stops not learned or lost after battery disconnect or repair
- PossibleActuator or selection linkage binding, target position not reached
- PossibleSensor or its magnet shifted, reading offset
- RareControl software needs an update
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
