Installation Notes

Board-level electronic repair and transmission-control diagnosis are required. Installation may involve opening the TCU, precision soldering, resealing, fluid-safe handling and subsequent diagnostic procedures. Confirm the fault before replacement; P0722 or P0723 can have causes beyond this sensor. Professional installation is strongly recommended.
