DESCRIPTION FUEL RECEIVER GAUGE OPERATION (a) OPERATION The combination meter assembly 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...
DESCRIPTION The power steering ECU assembly supplies a voltage of 5 V to the torque sensor (electric power steering column sub-assembly) and monitors the voltage value of the Hall IC inside the torque sensor (electric power steering column sub-assembly) which changes in response to changes in the magnetic flux density (steering torque) detected by the Hall IC, and calculates the assist torque...
