Which knock sensor to get for a 1998 SS? Hello gentlemen,
I am throwing a code for bad knock sensor in my 1998 SS. I have decided to replace both of them.
I am showing 10456222 as the correct part number for my car (includes locating tab).
However, there is also 10456603. Supposedly this is a 1998+ sensor with no locating tab. I did a search and some people have either/or.
Is there any reason I should buy one part number over the other? Will they both connect to the wiring harness and fit in the knock sensor hole just the same?
Seems the latter part # that I listed - 10456603 - has been updated and may have improvements. Plus, it's cheaper. Should I just buy this one? Assuming it will plug in and work of course.
Thanks,
Dope

I have always heard to get the 10456603 its the updated one that works.
On another note. I thought that if you ordered it from GM they get you the updated one. just like the oil pump. that they really dont list the old one.

You'll want the updated knock sensors and the harness. The new sensors have a different plug on top, and the "harness" is only about 2' long, attaches to the main harness right behind the manifold.
Knock sensors - 12589867 (you'll need 2)
Harness - 12601822
It may also be a good time to replace the intake manifold seals. I'd recommend these.....

They are cheap and will work on a stock manifold better than a factory set (they are thicker). Expect to pay $75 for seals from a dealershit. You don't HAVE to buy these, but seals that have been on for a while flatten out badly and don't work well. I just pulled my neighbors '02 'vette manifold and his were just barely at the "ok to put back on" level.
