My "diesel exhaust fluid range" is showing 4095 miles. It is interesting since my DEF tank was filled up when I purchased the car and I have since put 6k miles on it. My LVL is showing 100.
The Diesel Exhaust Fluid Range sensor seems a bit unique in the fact that the data range given to it doesn't appear to cover normal operational values. Normally parameters are given data ranges that go well beyond what's expected so that almost no matter what the reading doesn't go off scale. For example I've seen temperature sensors that have data ranges that go all the way down to absolute zero. The sensor itself would probably break before it would go off scale. However, in this case the DEF Range can easily exceed 4095 Miles, but that's the max reading it can show. I can only guess why that is as I don't know exactly how they measure the DEF level. Perhaps they only measure the DEF level at a point that's below the tanks capacity and consider anything above that just extra full.
Either way, I suspect that once the range actually drops below 4095 you'll see it start ticking down as you drive.
Can anyone tell me why there are 3 exh gas temp gauges and 2 intake air gauges? They all read different when I scroll thru them. Any info on why there is more than 1 gauge for each of them? If the temps are from different locations in the system, does anyone know where guage 1 is sensing from? Guage 2 sensing from? etc.
There are multiple Exhaust Gas Temperature readings since there are multiple points at which the exhaust gas temp is monitored. I believe EG1 is Post DOC and EG2 is post DPF, and as for EG3 I'm not sure. Usually people can infer where an EGT sensor is located based on what the temperature reads before, during, and after a regen occurs. Roughly the same explanation for the intake air temp readings. I'm not sure where they're located physically, but based on how they behave we can likely figure out where they may be.
- NCR Number of Completed Regens (#)
Does this one work for you? It does not work on the CTS.
My understanding is that the NCR XGauge being tested did increment up 1 after a regen was completed, so it's looking like it works for the ScanGauge 2.
