Circuit Description

The powertrain interface module (PIM) receives information from the powertrain control module (PCM) on the Class II serial data circuit. This information contains the current fuel level and the status of this information, is either valid or invalid. If the PCM detects a problem with the fuel level sensor information it will set a DTC P0461, P0462 or P0463. If DTC P0461, P0462 or P0463 are set in the PCM, the status of the fuel level information sent to the PIM from the PCM will be invalid, this will cause DTC B0575 Fuel Level Indicator Circuit to be set.
