low voltage error codes

loudenuf4u · #1 (**permalink**) 08-20-2007, 01:09 PM

My 99 f350 7.3 has been acting up. It has been coming up cam sensor. Well i was coming to a stop sign the other day and it died. Well no big deal i figured cam sensor. It didnt restart. I towed it home checked the codes and im getting low voltage cam sencor low voltage injector control prosser and low voltage to exhaust backpressure sensor. Well i changed the cam sensor, cleaned the backpressure tub, changed the fuel filter, unplugged the ICP to see if it would start, nothing. It has oil pressure when it cranks and oil is ok. I have 4 2400 cca battries, a few extra for the sound system. I reset the CPU and dont have any codes now but still wont run. HELP ME WITH MY BABY ANYONE!

it would help alot to have the codes you were dealing with, you also say you have oil pressure when cranking does that mean you have a scanner that will monitor data , if so also look at reference voltage and tel me what its reading

no i dont have a scanner just a code reader. here are the codes P0340, P0344,P0470,P1212,P1280. i cleaned the cables on the batts and now none of these codes come up.

p0340 and p0344 are cam sensor codes , p1212 and p1280 could be icp or ipr concern, if youve already changed cam sensor , really need to know if you have high pressure oil and have fuel pressure

i think i overlooked the real problem. i have pressure to my bowl but im sure it not going anyplace elese.

i replace the filter when it died but i never looked in the bowl. im sure it made into everything else. it acts like its not getting fuel

hmmmm hope its not Alleghent Ford in Pittsburgh. If they said it was your HPOP going bad, it's probably just a flat tire...note the sarcasim. But listen to Scuffy..he knows what he's talking about!
