What is the issue with the Buick Regal instrument display calibration?
1 Answers
This refers to the automatic calibration of data or status by the instrument system when the car is started, as part of the vehicle inspection. Here are the relevant details: 1. Car dashboard: The instruments vary between different cars, but generally, conventional car instruments include the speedometer, tachometer, oil pressure gauge, water temperature gauge, fuel gauge, charging gauge, etc. 2. Oil pressure gauge: The sensor of the oil pressure gauge is a piezoresistive sensor. It is fixed with threads to the engine oil pipeline. The oil pressure pushes the contact piece to move on the resistor, changing the resistance value, which in turn affects the current passing through the instrument to the ground, driving the pointer to swing.
