Toyota Camry's oil needle doesn't work normally, because it is normal to clean the throttle and turn on the others after the power failure.

Hello, many vehicles' fuel meters have compensation mechanisms to deal with road conditions such as turning, going up and down slopes, and instrument computers with the functions of average fuel consumption and remaining fuel mileage will also compensate the accuracy of fuel meters. When the power is cut off, this trace compensation data will disappear and the remaining fuel will be less than before. When refueling, the fuel indicator will return to normal after the new compensation mechanism is established. I hope the above answers are helpful to you.
