LB7 dead pedal 3 codes

[MackeyLB7]

I’ve had this truck for almost 5 years and have slowly built it up recently I put a stage 3 trans and t case in it and re learned the shift points about 30k ago for the past month I’ve been getting some codes and a dead petal now it’s setting them immediately the MIL is not on the codes are (P0237 turbo boost sensor A circuit low) (P0651 sensor reference voltage B circuit open) (P2228 barometric pressure circuit low) it does have efi live with dsp5

sounds lime you lost the 5 volt circuit. time to start checking the wiring and looking for chafed or broken wires. take a look at the harnesses that runs near the alternator for rub through and inspect all the pins in the large bale connectors. I think the oil pressure sensor may be on that circuit too.

Did you recently install a 3" intake horn?

 

[MackeyLB7]

Not recently but it has been removed and installed in the past

Is it possible my ecm is bad? Or is that not very highly the problem?

Looks like he doesnt know how to use the quote function, 2004. I think this is his reply to your thought.

it is unlikely your ECM is bad. more often than not it is a broken or shorted wire. or sometimes a bad sensor

Where would you start I already checked the pins for the ecm?

The reason why I asked if you installed a intake horn is because the wires can get pinched and will throw those codes that you are speaking off. I believe its either the MAP sensor or Barometric sensor wiring. Ask me how I know lol!

Yep and the truck ran great for like a day and then threw a code, I would definitely double check that wire and if it is smashed or cut then cut out that section and solder do not use wire crimps.
