P0877 Transmission Fluid Pressure Sensor/Switch D Circuit Low
The transmission fluid pressure sensor/switch D reports a circuit low fault. Hydraulic pressure feedback for shift control is unreliable on this channel.
Is it safe to drive with P0877?
The car may go into limp mode (reduced power). Get it diagnosed before a long trip.
Common causes
- Most likelySignal wire shorted to ground
- PossibleInternal sensor short
- Less likelyConnector pins corroded - high contact resistance
Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
