intake air temp sensor, '88 5kcstq, BTDT?

[auditude at neta.com]

I just pulled the codes on my '88 5kcstq, to see if there was 
anything there.  I was interested because of the check engine light 
coming on the other day.  It hadn't come on since, after I topped off 
the oil level.

I came up with code 2322, which the Bentley says is an intake air 
temperature sensor fault.

So, I thought I'd check for any BTDT's or things to look for before I 
start looking into it.  Is there anything special, besides what my 
single volume, early Bentley has to say about it?

Thanks,

Ken
