Question

i have a 2006 dodge magnum with a 5.7 l hemi, engine light has come on with a few lothers, its giving me a code of P0129, how do i fix this

Answer 1

P0129 Barametric pressure sensor out of range

P0401 EGR system performance

P0107 Map sensor circuit low

P0108 Map sensor circuit high

P2172 High airflow leak detected (instantaneous accumulation)

You have a vacuum leak , this can be from the EGR stuck open, P2172 automatically set MAP codes.so does P0401.Look for vacuum leaks at throttle body intake manifold,You may have to pull the EGR and inspect to see if the pintle is stuck in the open position.You realize you have a plastic intake manifold and this code P2172 is intended to limit maximum engine speed if large cracks occurs.Also make sure the throttle plate isnt binding
