P0191 is fuel rail pressure circuit, and P069E tends to be fuel pump control module issues.

By experience this can be bad grounds, MAP sensor issues (if it runs) and the fuel pressure sensor not on the rail, but right in front of the brake control assy.................. but remember to check the GROUNDS, Every rondome flaw in those I ever saw was due to RUSTED GROUND WIRES.

P0191 is injector pressure sensor system performance. Nothing on the other code with the letter mixed in. I would erase it and see if it comes back.

P0191


You need to have the fuel pressure checked, to see if the fuel pump or fuel filter may have a problem. The code is for the Fuel Rail Pressure sensor, and the reading from it is out of range.

P018b code


They are both fuel related codes. You should worry more about the repair than if you drive unless you want to drive it to get it repaired. The car will drive or will stall out. There is no definitive answer. Those are the only codes you get? Do you have any history codes?
