B3801 Lada 119 OBD Code

OBD/2 B3801 error code description and symptoms.

The Transmission Fluid Pressure Switch allows the engine's control module (PCM) or Transmission Control Module (TCM) to use hydraulic fluid to engage the clutches in the transmission to allow for smoother shifting while driving. If the PCM or TCM detects an issue with the hydraulic clutch or the pressure switch, the PCM or TCM will set code B3801

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code B3801, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code B3801 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
