Code C1423 2016 Toyota RAV4 Description

The C1423 diagnostic trouble code (DTC) for a 2016 Toyota RAV4 indicates a Master Cylinder Pressure Sensor Zero Point Low Malfunction. This code is typically triggered when the pressure sensor in the master cylinder, which is responsible for monitoring hydraulic pressure in the braking system, detects a reading that is lower than the expected zero point. This can be caused by a variety of issues that affect the sensor's ability to accurately measure pressure, leading to potential safety concerns and compromised braking performance.
