i just installed an autometer wideband gauge, it powers up but when I start the engine the gauge reads --- and every five seconds it flashes 19.9 it does as long as the truck is running, im getting 14.1volts at the gauge with everything plugged in and the engine running, I pulled the sensor out of the exhaust and still get the same reading --- 19.9 any ideas ,I think the sensor may not be reading but Im not an expert on these things.any help is appreciated. Thanks

I found the problem, I had the voltage but not the amperage to heat up the sensor all works ok now.
