B1500 LEXUS Meaning

The combination meter assembly (meter circuit plate) uses the fuel sender gauge assembly to detect the amount of fuel remaining in the fuel tank assembly. The Hall IC built into the fuel sender gauge assembly changes the output voltage according to the amount of fuel remaining. The combination meter assembly (meter circuit plate) detects the voltage output from the fuel sender gauge assembly and operates the fuel receiver gauge. During normal driving: As the fuel level in the fuel tank assembly changes when driving on a hill or applying the brakes, the fuel receiver gauge reading is updated according to the fuel injection volume during normal driving. However, as the fuel injection volume measurement has a margin of error, the value is indicated after correction by input values from the fuel sender gauge assembly. This Diagnostic Trouble Code (DTC) is stored when the Combination Meter Assembly (meter circuit plate) detects a Fuel Sender Gauge Assembly malfunction via a direct line.
