Last fall I changed the plugs in my '93 Sonoma. (VIN W) In the process, I
broke the plug on the knock sensor in the head beside the steering column
and finally got around to putting a new connector on the wire. It was
identical, so no problem there.
The problem I have is that I still get the code 43, so is the sensor bad
too? No problems before changing the plugs, but afterwards the connector
wouldn't stay on the knock sensor setting the check engine light off.
The check engine light comes on, and (I assume) once the temp sensor kicks
in the light goes out. Then it is good for the rest of the day.
Thanks for any help,

I;d still be looking at the wire. If it was broken and just dangling, it's
likely corroded now. Knock sensors rarely stop working as they're a very
simple beast. I'd run a continuity test between the connector and 2'-3'
I'll check that tomorrow. The plug didn't have a chance to corrode, I put
it back in each time the light came on. There's burned spot where the
protector came into contact with the manifold, I'll check there closer too.
Is the metal part of the plug supposed to come to a point, or is it broken
on the end?
