P0843 HONDA Description

Transmission fluid pressure switch A (2nd clutch) is installed in the hydraulic pressure circuit to the 2nd clutch. When hydraulic pressure is supplied to the 2nd clutch, the switch is turned ON. When hydraulic pressure is not supplied to the 2nd clutch, the switch is turned OFF. The signal from transmission fluid pressure switch A (2nd clutch) is input to the Powertrain Control Module (PCM). The PCM detects the hydraulic pressure supply conditions at the gear change to 2nd gear (1st to 2nd, 3rd to 2nd) to reduce the shock that occurs at the gear change. If transmission fluid pressure switch A (2nd clutch) is OFF while driving the vehicle with the rotation speed ratio of the input/output pulses is that of 2nd gear, the PCM detects a transmission fluid pressure switch A (2nd clutch) failure and stores a Diagnostic Trouble Code (DTC).
