Code P0237 2018 Honda CR-V Description

The Turbocharger Boost Sensor senses turbocharger boost pressure (vacuum) and converts it into electrical signals. The Turbocharger Boost Sensor outputs low signal voltage at high vacuum (throttle valve closed) and high signal voltage at low vacuum (throttle valve wide open). If the signal voltage from the Turbocharger Boost Sensor is a set value, the Powertrain Control Module (PCM) detects a malfunction and stores a Diagnostic Trouble Code (DTC).
