Code P0797 2020 Honda CR-V Description

The Continuously Variable Transmission (CVT) clutch pressure control solenoid valve controls hydraulic pressure to the forward clutch and the reverse brake. The CVT clutch pressure control solenoid valve is controlled by duty cycle output. The spool in the CVT clutch pressure control solenoid valve moves the valve according to the current and produces hydraulic pressure in proportion to the current. To supply proper forward clutch/reverse brake oil pressure, the Powertrain Control Module (PCM) outputs a CVT clutch pressure control solenoid valve oil pressure control signal. If the duration of the forward clutch/reverse brake engage operation from start to completion is short, the PCM detects a CVT clutch pressure control solenoid valve stuck ON failure and stores a Diagnostic Trouble Code (DTC).
