P2C8E: DC/DC Converter Temperature Sensor D Circuit Low
Standardized SAE J2012 code · P2Cxx codes
What does P2C8E mean?
The ECM detects a circuit low fault on the dc/dc converter 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.
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 P2C8E on the same make and model first.
