Hi there, new to this site. I got a code of P0004 fuel volume regulator control circuit high. What does this mean. I have noticed that my mpg has gone down. If you have a fix or suggestion my wife will love you. Also I received a B0010 drive knee bolster deployment control subfault any help will be greatly appreciated.

 

You sending unit may be bad or the sensor,
ff

 

Which one should I replace or is there a way to check if the sensor is bad? let me know.

 

Cleared the codes and I still get the P0004 fuel volume regultor control circuit high. Checked with napa there is nothing in there system called a fuel volume regualtor control circuit. Has anyone had this problem and the fix. ANy help would be greatly appreciated.

 

I would take it to Autozone and they can pull the cosed for free and offer a solution as I never heard of a code P0004. Usually the codes are p0xxx...
