Code P0848 2014 Chevrolet Silverado Description
The P0848 diagnostic trouble code (DTC) for a 2014 Chevrolet Silverado relates to the Transmission Fluid Pressure Switch 2 Circuit High Voltage. This code indicates that the transmission control module (TCM) has detected a higher than normal voltage signal from the transmission fluid pressure switch 2 circuit. The transmission fluid pressure switch is responsible for monitoring the hydraulic pressure within the transmission and sending this information to the TCM. When the voltage signal is too high, it can indicate a problem with the switch itself, the wiring, or the transmission system as a whole.
Common Causes of P0848 2014 Chevrolet Silverado
- Faulty transmission fluid pressure switch
- Damaged or corroded wiring/connectors
- Low transmission fluid level
- Internal transmission issues
- Faulty TCM
