Knock and Speed Sensor for I30

I have a 96 Infiniti I30. Just this morning the Check Engine light came
on. Went to Auto Zone and had them to use the computer to find out
what was wrong. Got codes P0325 & P0500. Seems the Knock(170.00) and
Speed Sensor (150.00)need to be replaced.

The question I have is this a DIY job or should I be looking to take
this to the shop. If so where are these located and how do I replace
them?

Thanks.

Auto zone!?
How do you/they know what the real cause of the CEL is?
Randomly replacing parts can get very expensive.

Knock sensor isn't hard to get to on these. Dunno the other one. You can
download the 96 Maxima factory service manual for a small fee online. You
get a couple of days access, so you can get any Nissan manuals you want.
Don't know about Infinity-specific ones--do a web search for more info.

While knock sensors can fail on this car, you can also get spurious knock-sensor
codes. And the knock sensor code doesn't trigger the CEL. So after clearing it,
you should check it again before embarking on the diagnostic procedure (which
I think is: Check connector. Bad? Replace. OK? Replace sensor). If the code
comes back immediately, deal with it. .

Might get better info at alt.autos.nissan.maxima.
