Chevrolet Sail Fault Code Engine Sensor Voltage Low?

Honey, this Chevrolet Sail fault code indicates that the engine sensor voltage is low. This is a problem with the throttle position sensor, which measures the position and opening of the throttle to control the fuel supply of the engine. If the sensor has the problem of low voltage, it will lead to unstable engine performance or poor acceleration. There is also an air temperature sensor, which measures the intake air temperature and helps the engine control the fuel injection and ignition timing. Too low voltage will lead to incomplete combustion, decreased fuel-saving performance or unstable engine operation.
