B1500 LEXUS, TOYOTA: FUEL SENDER OPEN DETECTED
The combination meter assembly, known as the meter circuit board, employs the fuel sender gauge assembly in order to sense the quantity of fuel available in the tank. A Hall IC that is integrated into the fuel sender indicator assembly is responsible for varying the output voltage stated into the amount of fuel remaining. The combination meter assembly senses the voltage output and operates the fuel receiver indicator.
Under ordinary driving, when the fuel level changes in the tank assembly, for example, when driving on slopes or applying brakes, the receiver gauge reading is updated according to the injection volume during normal driving. However, because the injection volume measurement has a margin of error, that value is displayed upon correction by the input values of the fuel sender gauge assembly.
The B1500 OBDII fault code is set when the combined gauge assembly detects a malfunction of the fuel sender gauge assembly through a direct line.
B1500 OBD2 diagnostic code is stored for the following reasons:
