I replaced both, with the harness all a/c delco new. Codes came back fairly quickly. 327&332 low voltage. Both new ones ohmed out at high 900’s. Where does the low voltage come from? My next thought is to start going through all of the multi pack connectors and ecm connections looking for corrosion. Any other ideas? Anyone?
I changed twist and the problem still an my 2000 GMC Sierra 1500 I test and give me 1500 onna stii the check engine I don't know what it's the problem??
Hey James, I’ve been watching your videos regarding knock sensors as well as (IAC) valve test and replacement. I have a 2000 Chevy Silverado with a 5.3 vortec. I have recently had a local shop replace the knock sensors and ever since then I have a code p0507 for high idle. I took it back to the shop as I did not have this code before and they cannot find the problem the iac functions properly with the ecu. The truck will slowly accelerate to about 30th on its own and maintain speed as if cruise control was engaged when letting off the accelerator. Would a vacuum leak cause this? I have no idea what can be the problem!
I have already checked cruise control cable and bought a different iac and tps to test if there would be a change there is no change in the high isle speed. However, when I come to a complete stop while driving the rpm’s drop to around 700-800 like normal. Any suggestions would be helpful thank you!
Great videos Jim! Glad to see your doing well.
What voltage were you getting out of the good sensor when you were doing the knock test?

I got a bad knock sensor wire for bank 2 it's a 2005 4.8 liter So where how can I jump this wire w/new wire to ecm?

Did you change the harness to.
