Pressure sensor [A] 2-6 Brake 3-5-R Brake MAZDA FW6AEL FZ01-21-2C0 FZ01212C0

​   The oil pressure sensor senses the oil pressure that is applied to the clutch packs, which are made up of friction elements. The pressure sensor determines whether the required pressure is applied to the clutch packs depending on the selected driving mode, speed and gear selected. If the sensor detects that the pressure is insufficient or does not correspond to the specified factory parameters, during a certain driving mode, there are problems with gear shifting, and the signal comes from the sensor to the TCM from it to the vehicle's on-board computer in the form of an error code.
      Pressure sensor A has two switch sensors. on the image]. This sensor monitors the pressure in the clutch packs 2-6 Brake which is involved in shifting 2-3, 5-6 gears and 3-5-Reverse which is involved in 3-5 shifting and reverse gears, respectively.
      The sensor has a two-pin connector that connects to the TCM through the valve body internal wiring harness, namely a connector with red and white wires like pressure sensor B.
