Greetings,

Can someone can describe location of the knock sensor on a '91 Corsica 3.1L V6 and how to get at it?

Been unsuccessful in forum search (probably me ) and Haynes manual is vague.

Thank you for any help.

note where it is located.
Check the wiring to it to see if it may be burnt by the exhaust

@rockfangd - thank you for the follow up.

The CEL error is infrequent and intermittent. My son, who drives the vehicle regularly, claims he's never seen it. I rarely drive the vehicle but the last 2 time I did the CEL flashed on a few times, usually over a bump.

Your observation kind of fits. The insulation could be compromised and causing a short.
