Hi to everyone i have 2004 lincoln navigator 4wd (220000km), recently i have check engine light on, scan tool reading code P0182 which is for fuel temperature sensor A low voltage, did some research and find out this obdII code is for natural gas truck, regular truck doesn't have fuel temperature sensor. anyone know any idea, truck has to go for emission test and with check engine light it will fail the test. Do i have to change PCM and reflash it by dealer or any other clue ......... appreciate that thanks

 

But the flex-fuel ones do. Follow the entire fuel rail and see if you can find the item indicated by the red arrow in this picture.

 

Thanks for your reply, i think you are talking about fuel rail pressure sensor, 2004 navi is not flex fuel truck. I will try to change this sensor. Is there any thing else I can try
