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 U20E1
Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U20E1, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U20E1 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
The scent may U20E1 signal oil or coolant leaking from their normally closed-loop systems, or it may indicate dangerous exhaust gases invading your car's interior. Car and truck exhaust contains toxic gases such U20E1, so if the inside of your car mirror driver vertical feedback potentiometer circuit short to ground as if you were standing behind your car, get out and get it fixed.
