They usually just go dead when they break. Or get low. I would check all your grounds. Engine. gauge. battery, etc. Thermocouples work on very small voltages. Bad grounds can really mess them up. Check for cable damage. You would have to look up the voltages but you could use a milivolt voltmeter to verify if it is the probe. I think if memory serves it should be about 22 (I think) mv at 1000 degrees F . If it is ok it could be the gauge.
