Code P0872 2014 GMC Sierra Description
The P0872 diagnostic trouble code (DTC) for a 2014 GMC Sierra indicates a Transmission Fluid Pressure Switch 3 Circuit Low Voltage. This code is typically triggered when the powertrain control module (PCM) detects that the voltage signal from the transmission fluid pressure switch 3 is lower than the specified threshold. The transmission fluid pressure switch 3 is responsible for monitoring the hydraulic pressure in the transmission system. When the voltage signal is too low, it can lead to improper shifting, decreased fuel efficiency, and potential damage to the transmission components.
Common Causes of P0872 2014 GMC Sierra
- Faulty transmission fluid pressure switch 3
- Wiring issues or loose connections
- Low transmission fluid levels
- Internal transmission problems
- Faulty PCM
Symptoms of P0872 2014 GMC Sierra
- Rough or delayed shifting
- Transmission slipping
- Reduced fuel efficiency
- Illuminated Check Engine Light
- Transmission overheating
How to Fix P0872 2014 GMC Sierra
- Begin by checking the transmission fluid level and quality. Top up or replace the fluid if necessary.
- Inspect the wiring harness and connections related to the transmission fluid pressure switch 3 for any damage or corrosion. Repair or replace as needed.
- Test the transmission fluid pressure switch 3 using a multimeter to ensure it is functioning correctly. Replace if faulty.
- Clear the DTC from the PCM memory using a scan tool and test drive the vehicle to confirm the issue has been resolved.
- If the problem persists, further diagnostics may be required to identify any internal transmission issues or PCM faults.
Cost to Fix P0872 2014 GMC Sierra
