I have a 2000 F150 with a 4.6l that I drive daily. Today the oil pressure gauge went down in the "red" and the oil light came on. I shut it off and cranked it and it was fine but later down the road it did the same thing. It did not make any noises or anything that led me to believe that something was wrong. Could this be a bad sending unit or, could it possibly be the oil pump going out?

 

anyone?

 

um wrong forum!

L's dont even have 4.6's.

post in the right forum and maybe somebody can help

 

Well I know its the wrong forum, and that lightnings dont have a 4.6L but they are practically the same motors. i just thought someone could help me out.

 

off to the correct forum...

 

The 4.6 & 5.4 sending units are famous for going out. i think there was a tsb on it.

 

I have had the same problem with my wife's 01 SportTrac. I know not the same truck, much less motor but exactly the same symptoms. Oil Pressure Sending Unit gone bad according to the dealer. They replaced it and that was the end of that problem.

 

The sending unit is going bad, replace it. They're under $10 from the dealer and are relatively easy to replace. It's best to change them during an oil change.
