In case anyone else runs into this, hope it helps!!



You said you changed the “venturi that hooks to the vent valve line and the second inlet sensor” which one is that exactly. I have the same code 191C02 and my cel keeps popping up after i clear it about 20-30 miles. I have already replaced gas cap and dtml pump. This would probably help me
It is part number 13907601515 they call it the fuel tank breather line. That solved the returning code for me.
