For the new members wondering if 100 or 200k is high miles

what the hell IS a knock sensor? I will get a code for it then it will go out and not be in the memory then it will come back.

They read frequencies in the engine to see if there is preignition/detonation, and pull timing to save the pistons

I have a 01 yukon slt with 330,000 miles on it with no major issues. Under the hood the biggest thing I've replaced was the water pump and radiator. It also has over 10,000 hours, they only go up to 9999 so it's turned over but I haven't looked at it in awhile. It's still running good.

Same here, the MPG has also never been reset. So over its entire life its averaged 17.1 mpg.

Geesh that's pretty good, I only average about mid 14's mpg. If I run the mountains around here and use the a/c alot it will be in the high 12's low 13's.

Rolled on 200k with my 04 Tahoe Z71 just this morning.


Oil pressure is great. Charging is good. Cooling is consistent and good. Shifts good. Great daily driver for me!
Speedo needle is off by 7 mph and gas gauge is off by a bit more than 1/8 (PO put on the white cluster decals and didn't quite get those to needles in the right spot).

Front Airbag Impact Sensor replaced last week.
Replaced dead starter two weeks ago.

Work shortly after I bought it in Oct 2021...
Front left ABS speed sensor
Front & rear pads/rotors
Rear calipers

That's it over six months I've owned it. Brakes need to be done anyway. The rear pads were down to metal and the calipers were seizing.
