My check light is on... Codes are.. P0237, P0238, P1475, P0523, I had the codes checked today. Replaced the MAP sensor and the Oil pressure sensor and hade the codes cleared. Started the truck and in a min. I hade the codes again, so I cleared them again but still they keep coming up. I tput my truck in limp mode and has no power..... My dash lights keep blowing the fuse when I turn them on, Could this be linked somehow... Please help....

 

ok..i assume its a 24 valve?....i don't know the codes...what did tey tell u the codes mean?....does the truck rev or not? or is the tranny slipping? and staying in one gear?

 

yes its a 24 valve, codes were Map sensor volt to low, mapsensor to high, Aux power to high, oil sending volt to high. Dont rev, its a five speed no slipping

 

before I did any thing else I would check and clean all the ground connections and check the batteries and there connections. With several diffferent codes it could just be an electrical problem even a short some where.

 

Figured it out!!! Edge comp box is bad, works intermitent.. sending it back for repair. Still cant figure out the dash lights though, checked all grounds and had the dash out, no bad wires. I'm think I have a bad dimmer switch.
