Engine light P2097 error code help

[jbh1860]

Hey guys,
I got the check engine light while cruising down the interstate the other day. I checked for the code using the key/odometer and it comes up P2097. I can't seem to find much info on this code and was wondering if anyone had any experience or info. It's a '05 base PT w/ 44k miles. Car seems to be operating normal.
Thanks.

You'll notice that there are a number of possible causes for this fault. If you have some experience with automotive repair you may be able to check a few of these possibilities out on your own, however keep in mind that the diagnostics are written for trained auto technicians who also posses the necessary test equipment.

Given that this is an intermittent issue it may be somewhat difficult to accurately diagnose unless you can duplicate the issue. The dealer will experience the same difficultly troubleshooting the issue unless they can reproduce the problem at will. Regrettably, you may have to wait for the component in question to fail before you can obtain an accurate diagnosis.
