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 U3331
Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code U3331, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code U3331 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
If your fuel restriction condition check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system U3331 and engine control unit are in charge of monitoring a bunch of different fuel restriction condition, and if they get a reading that's a little out of whack, up pops the check engine light.
