DTC B0533: Fuel Level Sensor Short To Battery: Description

PZM monitors fuel level, and transmits this information over class 2 serial data line to Powertrain Control Module (PCM) and Instrument Panel Cluster (IPC). When ignition switch is in RUN position, PZM continually measures voltage at Brown 24-pin connector C1, terminal B12 (Purple/White wire) and determines position of sensor by calculating percentage of IGN-1 voltage present at terminal.

DTC B0533 will set if percentage of IGN-1 voltage at PZM Brown 24-pin connector C1, terminal B12 (Purple/White wire) is greater than an acceptable level for at least 2 seconds. PZM will send a class 2 message to PCM that percentage of IGN-1 voltage is too high. DTC B0533 will clear if percentage of IGN-1 voltage is less than or equal to an acceptable level for at least one cycle.

NOTE: If DTC B1982 or B1983 is current, DTC B0533 will not be set, but a class 2 message will be sent to PCM that percentage of IGN-1 voltage is too high.
