89 Liberty error code 24

[pete]

Gday,
My 89 Liberty MPI has started idling cold @ around 2000rpm then drop
down to about 1000rpm then the check engine light flashes on and
returns to 2000rpm.
It only started doing this after I gave it a thourogh clean in the
engine bay, It didn't do it just after the clean but started after
sitting in the garage for about a week..
I pulled the error code and it shows 24 - Temperature sensor

Has any one sufferd a similar problem because I cant fault the temp
sensor on the top of the engine??

I got it sorted out the Air flow solenoid was stuck 1/2 open.
