Engine codes

[FrostByte]

I got an engine warning light the day after changing my spark plugs. Advance auto's handheld code reader said "fuel rail pressure sensor malfuntion".
I had a weak fuel pump last year & it was changed (GT 40 super car pump) & got no more codes. Is it definatly the fuel rail pressure sensor or could Advance auto's code reader just pump out a generic code for fuel/deliv/press problem or should I believe it is the fuel rail sensor?
I am worried that fuel pump might have to be changed again. I picked up a new fuel filter & filter chaging tool & will change fuel filter just in case. I checked all the connectors since maybe we didnt get a connection tight after changing the spark plugs. I tried several times on way home to get code again by getting on it hard up thru 4th gear. No light. Since the code was cleared @ Advance Auto I cant recheck code @ a ford dealer to see if we get same error code diagnostic.

BTW its s stock 4.6L 2v with a ATI Procharger SC @ 8lbs. 255lph should be plenty of fuel pump.

It's worth a try, the worst that will happen is you replace something that's bound to break sometime...

Although a bullshit hand scanner will sometimes help it will not do everything that a ford factory computer will. just because you cleared the codes with that thing it does not mean that a real dealer scan tool will not get the code. depending on the scanner it will stay as a stored code not an active code. if you remember what the code was and you still have a problem let me know.

and why would you be changing your fuel filter when the code is for you fuel rail pressure sensor???

A small consumer OBD-II scanner will delete all codes... But will not log any of the codes like a professional one does. And it doesnt hurt to change the fuel filter especially with a blower car.

if it trips the same code again sometime soon check the voltage on the sensor. I'll have to see what the specs are on it and i will let you know.
