Code B2328 RAM Description

The B2328 diagnostic trouble code (DTC) indicates a problem with the washer fluid level sensor circuit, specifically that the circuit is reading a high voltage signal. This code is prevalent in various vehicle makes and models, particularly those equipped with advanced electronic systems. The washer fluid level sensor is designed to monitor the fluid level in the washer reservoir and send this information to the vehicle's onboard computer. When the sensor detects that the fluid level is above a predetermined threshold, it sends a signal indicating that the washer fluid is full.
