No one can answer that. You could post pictures of how the meter is connected, the meter setting, and the reading on the meter if in doubt.
To be clear......with the harness plugged in to both knock sensors.....you are individually reading the resistance at the harness connector C112 ?
For simplification - red lead of meter probing pin A OR B of C112, and black lead connected to battery ground?
....anything Dorman is questionable.

My new USA made NAPA knock sensors are here. Did some checking and had 266 Kohms at the harness end of the sensors, way above what the diagnostic flow chart indicates should be there. Just to check, the connector going to the PCM was showing 9.56 kOhms, so I think that side is good. Installed the new sensors, torqued to 15 ft/lbs and reinstalled my harness which was just purchased earlier this month and I'm still getting 199.3 kOhms. Am I reading my meter incorrectly, or is maybe my new harness bad? The harness I just installed is the Dorman harness.
If you are not confident in reading your DVOM or in your circuit testing take it to a professional.

Lucky, thanks for the reply. Went back out this morning and hooked up my DVOM as you suggested and got a reading of 99.6 kOhm which is within the diagnostic parameters. Everything is back together and it runs well! Hopefully this is the last of my KS trials!!!
