Code P0706 2020 Honda CR-V Description

The P0706 diagnostic trouble code (DTC) for the 2020 Honda CR-V indicates a Transmission Range Switch Open. This code is typically triggered when the powertrain control module (PCM) detects an open circuit in the transmission range switch, also known as the neutral safety switch. The transmission range switch is responsible for indicating the gear position (Park, Reverse, Neutral, Drive) to the PCM, allowing the vehicle to start and shift gears properly.
