OBD-II DTC P1352 – Fuel Level Sensor B Range / Performance

DTC P1352 meaning

DTC P1352 refers to a diagnostic trouble code indicating an issue with the Fuel Level Sensor B. This code suggests that the performance or range of the fuel level sensor is outside the expected parameters. The fuel level sensor is responsible for measuring the amount of fuel in the tank and relaying this information to the engine control module (ECM). When the ECM detects a discrepancy in the sensor’s readings, it triggers this code.
