P0038 Dodge -

Question

Engine light turns on.....pull out the obd scan. got two codes p0052 & p0038. laughed & said "childs play"
replaced all 4 o2 sensors. cleared the codes but one code wont clear the p0038.
figured faulty sensor...bought another one replaced it again. still wont clear!!!! help!!!

did i get 2 faulty sensors? do i have a serious electrical problem or maybe some type fuse problem causing surges?

Answer 1

HI there,

It's likely an issue wth the wiring to the sensor or the pcm itself keeping this code going. There isn't a fuse in the system, power comes from the pcm.
