P2E12: Gear Selection Actuator Position Sensor Circuit Low
Standardized SAE J2012 code · P2Exx codes
What does P2E12 mean?
The ECM detects a circuit low fault on the gear selection actuator position sensor. Reading cannot be used reliably for control.
The code tells you which monitor failed, not which part is broken. Test before replacing parts.
Common causes
- High Signal wire shorted to ground
- Medium Internal sensor short
- Low Connector pins corroded - high contact resistance
Likelihood is a general estimate across vehicles; your make and model may differ.
Add your car to see reports of P2E12 on the same make and model first.
