so what do i do to attempt to fix it?
Ok... Time for litle update. I hope experts chime in and help me with this.
I installed new purge valve and flow sensor for EVAP system and allso electric EGR controlvalve. Codes killed.
But I still have few codes to kill... P0133, P0153, P0156, P1232 and P1000. I visited at local Ford dealer and we connected VDS system to my car and checked hego signals. Front hegos are both laying at about 0.5v and very litle switching. Nothing like normal rapid 0.2v-1.0v switching should be. Both front hego sensors are only one year old. Heater circuits are fine and full voltage. And wireing loom looks like to be ok. No exhaust leaks. Why they act so wierd?
And that P1232... What was the idea with some former owner when he disabled that system? Resistor wires are connected together and one wire from relay is ripped off. So fuelpump is getting full voltage all the time.
