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.
• | The ignition is ON. |
• | The ignition voltage is between 5 and 17 volts. |
PIM has received invalid fuel level sender information.
The Check Powertrain malfunction indicator light (MIL) will not be activated.
• | A Last Test Failed (current DTC) clears, after the ignition has been cycled and the PIM receives valid fuel level information. |
• | The PCM receives the clear code command from the scan tool. |
The following DTCs may also cause this DTC to set: PCM DTC P0461, P0462 or P0463. These PCM DTCs should be diagnosed first.
Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
The numbers below refer to the step numbers on the diagnostic table.
This test confirms that the Powertrain OBD System Check has been performed.
If DTCs U1000 or U1001 are set, these PIM DTCs should be diagnosed first.
This test determines if any DTCs are stored in the PCM memory. To determine if a DTC is current, select "DTC Information / Failed This Ignition".
This test confirms if the DTC is current.
