pt check engine light

[johnnyb]

ok, got a puzzle for you...my wife has a 06 pt cruiser with 52k on it, she was driving it home last night and stopped at a red light and said that when she took back off the check engine light came on, and stayed on until she got home....ok, so i get out this afternoon to pull the code off of it and see what it means, i get in (the light is still on) and cycle from acc-on-acc-on-acc-leave on, and it dosent pull any codes, the mileage stays on the odometer...has the code cleared itself and the light will go off after some set increment? or am i pulling the codes wrong?

You should have at least been able to see DONE when you are finished. When I try the on, off thing, I NEVER get even the done. It seems that I cannot get a fluid motion and it gets hung up, not smooth.

ok, didnt realize it had to be done that fast, i tried it fast ant got one, then done

now what exactly does this mean?

P2097 or P2099 Post Catalyst Fuel Trim System High Limit

Go to Google and type or cut & paste Chrysler P2097 or P2099, Google will tell you the codes and the reason. From there I don't know. Did you do a search on this website?

Extensive search on Google only gives the definition of the codes, not what to do, but analyzing what it seems to mean, is that the 02 sensor (the one near the CAT) is reading a bad signal and may need changing.

Best thing to do is take off the negative battery cable for a few minutes to clear the code. If it comes back, change the sensor.

tried this and got the same thing as crewzin basiclly the definition of the code and found nothing on this site about it , it cleared itself this evening when we cranked it up after church, maybe it was a one time thing and wont come back....the wife said it came on after she got on it kinda hard "by accident"...guess theres no need to worry unless it comes back, thanks for the advice tho all!!!
