OBD-II DTC B1482 – Wiper Washer Fluid Level Sensor Circuit Short To Ground
DTC B1482 meaning
DTC B1482 refers to a diagnostic trouble code indicating a short circuit to ground in the wiper washer fluid level sensor circuit. This code is part of the On-Board Diagnostics II (OBD-II) system, which monitors various vehicle components and systems for faults. The wiper washer fluid level sensor is responsible for detecting the fluid level in the washer reservoir and sending this information to the vehicle’s control module. A short to ground means that there is an unintended connection between the sensor circuit and the ground, which can lead to incorrect readings or a failure to detect low fluid levels.
