B0532

CIRCUIT DESCRIPTION
The fuel level sensor changes resistance based on fuel level. The IPC monitors the signal circuit of the fuel level sensor in order to determine fuel level. When the fuel tank is full, the sensor resistance is high and the IPC senses a high signal voltage. When the fuel tank is empty, the sensor resistance is low and the IPC senses a low signal voltage. The IPC uses the signal circuit of the fuel level sensor in order to determine fuel gauge position. The IPC sends the fuel level percent via the class 2 serial data circuit to the PCM for misfire and EVAP diagnostics.

CONDITIONS FOR RUNNING THE DTC
The ignition is ON.

CONDITIONS FOR SETTING THE DTC
^ The fuel level signal is less than 3.5 percent.
^ The above condition is present for greater than 2.5 seconds.

ACTION TAKEN WHEN THE DTC SETS
The fuel gauge defaults to empty.

CONDITIONS FOR CLEARING THE DTC
^ The DTC becomes history when the conditions for setting the DTC are no longer present.
^ The IPC receives the clear code command from the scan tool.

TEST DESCRIPTION

Steps 1-10:

The number(s) below refer to the step number(s) on the diagnostic table.
3. Tests for the proper operation of the circuit in the high voltage range.
