The reductant temperature sensor helps ensure that the DEF is at the optimal temperature for the SCR system to effectively reduce harmful emissions.
Common Causes of P10C8 Chevrolet
- Faulty reductant temperature sensor
- Wiring or connector issues in the reductant temperature sensor circuit
- ECM software glitch or calibration error
- Contaminated DEF fluid affecting sensor readings
- Environmental factors such as extreme temperatures affecting sensor performance
