2000 Yukon XL 5.3
I'll bullet what I've done..
-Got one of the standard knock sensor codes and CEL
-Replaced both knock sensors and the wiring harness, properly cleaned and torqued etc.
-BOTH pending codes P0327 and P0332 come up within a couple minutes of running after every time I reset them. (Yes, they are plugged in, it's the first thing I checked!!
-CEL comes back on in about 15 miles with 2 warmup cycles
-I have cleared the codes, and disconnected the battery to clear everything out, and they still come back.
-99.7 Ohms at with truck off
-109.9 Ohms with engine idling. Both sensors are within a tenth or two measured at the plug end of the new harness.
Checked wiring back to harness, and roughly checked under the fuse box to make sure nothing has been living in there and feasting on my wires, it was clean.
So, What do I do to get this thing to settle down?
