Engine/Transmission (1998.5 - 2002) codes: 1693, 0251,0463

[racerman50]

My 1998. 5 24 valve, 191k, is starting, idling and running fine. Did a new remote lift pump 1 year ago. No problems since other than replaced APPS 4 months ago.

What might I be looking at with the 0463 and 0251 codes ? I prefer to drive it and forget it. :-laf

Thanks,

David

Thanks.

I'm okay with "Fuel level sensor input above acceptable voltage". The fuel gauge has had a mind of its own for the 3 years I've owned it.



OTOH, with "Problem sensed with fuel circuit internal to fuel injection

pump" I'd like to hear that I'm not on the verge of VP44 failure. I thought those puppies just quit all of a sudden.

Any more advice / info on P0251?

Thanks!
