2001 Buick Regal Question: Knock sensor pin location at the ECM



KGrandd, White House, TN, July 18, 2014, 09:15

I have a 2002 Buick Regal LS. I replaced the knock sensor (slow response)to get rid of the engine light and that didn't fix the problem.
No 5v at the harness side connector.
Not going to ground.
My question is what pin # or where do I check at the ECM module to make sure the knock sensor wire is not broken and getting to the ECM.
Thanks for any help
