Do you really have to remove the intake manifold before you can remove the knock sensor? I have a '93 (non-turbo). The Haynes manual says you do, but from pictures that I took with the motor still intact, I am wondering if you absolutely have to. I can't tell now.
I had to do some work on my motor which required removing the intake manifold. After I pulled the manifold off, I noticed that the plastic housing of the knock sensor was cracked. I haven't ever had any error codes come up, but I don't know if the part is actually a problem or not (I read in another recent post "Knock Sensor", that sometimes the CEL light won't come on for this error). Anyways, I don't want to replace the $60 part unless I have to. The resistance is reading 574k (ohms). Is that considered "Continuity"? Seems pretty high for continuity, but I really don't know.
Anyways, I am hoping to put the motor back together, run the engine for awhile, and then check the codes (Since again in the post"Knock Sensor", it says that code 22 can come up without the CEL coming on). But I don't want to have to remove the intake manifold a second time!
I would appreciate any info that people can provide on either of these questions.
Thanks,
Paul

No you don't its very easy to replace. Use a few extensions on a 12 or might have been 10mm socket. Remove bolt, and pull out sensor. Carefully unplug the connector!
When you put the new sensor in be sure to not tighten the bolt very much. The torque spec on it is something like 13-15ft-lbs. Or you can basically go snug.
