P0847 ACURA Description

  The 3rd clutch transmission fluid pressure switch is installed in the hydraulic pressure circuit to the 3rd clutch. When hydraulic pressure is supplied to the 3rd clutch, the switch is turned ON. When hydraulic pressure is not supplied to the 3rd clutch, the switch is turned OFF. The signal from the 3rd clutch transmission fluid pressure switch is input to the Powertrain Control Module (PCM). The PCM detects the hydraulic pressure supply conditions at the gear change to 3rd gear (2nd ??3rd, 4th ??3rd) to reduce the shock that occurs at the gear change. If the 3rd clutch transmission fluid pressure switch is ON while driving, and the speed ratio of the countershaft to the mainshaft is other than the 3rd ratio (the ratio is Neutral or 4th), the PCM detects a 3rd clutch transmission fluid pressure switch failure, and a DTC is stored.
