Code P0793 2021 Honda CR-V Description

The Continuously Variable Transmission (CVT) drive pulley speed sensor is attached to the outside of the end cover. The CVT drive pulley speed sensor detects the number of revolutions of the gear on the drive pulley and sends a pulsing signal to the Powertrain Control Module (PCM). The PCM converts the pulsing signal into drive pulley speed. If no pulses occur with the drive pulley rotating, the PCM detects a malfunction that may be caused by an open, an intermittent open, or a short to ground. Based on the correlation between the CVT drive pulley speed sensor and the torque converter turbine speed sensor, the PCM detects a malfunction and stores a DTC.
