P0877 Code: Easy Steps to Solve It
The P0877 trouble code is a diagnostic trouble code (DTC) indicating an issue with the Transmission Fluid Pressure Sensor/Switch “D” Circuit Low. This code is triggered when the powertrain control module (PCM) detects that the electrical signal from the transmission fluid pressure sensor is below the expected range. This can lead to various transmission performance issues, making it essential for vehicle owners and DIY mechanics
