Code P0843 2017 Honda CR-V Description

The Continuously Variable Transmission (CVT) driven pulley pressure sensor uses a strain gauge. The output voltage changes depending on the driven pulley pressure. The Powertrain Control Module (PCM) sends a 5 V reference voltage to the sensor through a pull-up resistor. When the driven pulley pressure is low, the sensor resistance decreases and the PCM detects a low signal voltage. Conversely, when the driven pulley pressure is high, the sensor resistance increases, and the PCM detects a high signal voltage. If the CVT driven pulley pressure sensor signal voltage is a specified voltage for a set time, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
