P2E50: Battery Charger Coupler Temperature Sensor D Circuit Range/Performance

Standardized SAE J2012 code · P2Exx codes

What does P2E50 mean?

The ECM detects a range/performance fault on the battery charger coupler temperature sensor d circuit. Reading cannot be used reliably for control.

The code tells you which monitor failed, not which part is broken. Test before replacing parts.

Symptoms

  • Charge status indicator shows fault
  • Charging may not start or interrupts
  • Slower-than-expected charge rate

Common causes

  • High Sensor characteristic drifted
  • Medium Sensor mounting displaced
  • Low Sensor element aged beyond calibration window

Likelihood is a general estimate across vehicles; your make and model may differ.

Add your car to see reports of P2E50 on the same make and model first.
