OK, first thing to know about doing auto gauge repair is that this isn’t really a do-it-yourself job. In modern production automobiles, trucks, and vans, when a problem crops up in the gauges it’s not something to try to tackle on one’s own. Beyond the fact of how much of a hassle it is to get to the gauges in the first place, which in most cases involves removing the entire dashboard, there’s the complexity of the instruments in today’s vehicles to be confronted.
Electronic instrument panels require proper voltages to operate as designed. When the panel is not getting the flow of current needed, the driver gets erratic display issues, such as 8s appearing as 0s or vice-versa, inaccurate information, and finally a blank display. Now, sometimes this is a simple issue involving a faulty fuse or a minor grounding problem. But if a new fuse blows almost as soon as it’s installed, then there’s a deeper problem involved such as a short in the wiring harness or the instrument circuitry. Professional technicians who regularly provide services for Auto Gauge Repairs in Tucson AZ will first examine the circuitry with an ohmmeter and a voltmeter to run down a short or a grounding problem. If the fault is not down to either of these, then obviously a deeper circuitry problem is involved which is definitely beyond the competence of the driver or the shade-tree mechanic to deal with.
Modern gauges depend upon digital sensors to provide the readouts for display. While this has massively improved precision in the information reaching the driver, the corresponding complexity in the system has multiple points of potential failure. These can cause a host of different problems such as one or more gauges which read higher or lower than the actual performance range of the particular engine system being measured. Erratic display is another potential problem arising from a sensor or processor malfunction or wiring fault. Sending units which transmit the information may also be suffering one or more problems which can cause faulty display.
