2007 Taurus CEL code information
 

I have a 2007 Taurus with 219,000 miles on it and this week the Check Engine light came on. I took it to OReilly and had them scan it. The codes came back P1235 and P0191. The car was running fine. I reset the code by disconnecting the battery for a few seconds and it has been about 200 miles and the light hasn't came back on. Any help would be greatly appreciated. Thanks Henry

Today the CEL came back on and it showed the P1235 code and P0456 code. Please anyone with knowledge of this let me know what to do. Thanks
