XG300 sets code 1151, Help please Hyundaitech?

I've posted before about my 2001 XG cutting out to limp mode only twice in
about a year. Both times I got it to run perfectly again for many months by
disconnecting the battery & then restarting. Well today it finally did this
again but this time I had an Code reader with me. So it sets the 1151 code
which is a malfunction as in either an open or short for the APSII. Now
here's where I get confused by the manual as this car has 2 accelerator
sensors -one located at the end of the throttle cable & the other on the
side(s?) of the throttle body by the air intake after the Bosch Mass air
flow sensor housing. Since the manual seems to call these parts both a TPS
or an APS & seems to switch the numbering about whimsically (ie. the TPS1 is
the same part as the APSII ???), I'm not sure where I should be looking for
basically a bad connection, if I understand the manual's intent.
Thanks,

The one by the strut tower is the accelerator position sensor. The one on
the throttle body is the throttle position sensor.

You have excellent chances of repairing by replacing the accelerator
position sensor. I've never seen this code (on the XG) in a situation
where the problem was elsewhere.

 

Thank you so much for your time & effort to reply -VERY much appreciated. We
live in such a remote part of the world that seriously just getting to a
dealer to have the vehicle checked & then returning a week or so later after
the part came in would cost way more than the service itself.
We want to wish you & yours a very Happy Holiday Season & I'm sure that is
a sentiment wide spread on this news group.
Sincerely,
