1993 2.3 O2 and RPM codes...
Ok yall can i get some help to get these pesky things figured out . so im getting codes...
172 -(HEGO2 sensor voltage indicates "lean") 411 -(Cannot control RPM during Engine run self test--Low RPM check) First the O2 sensor....does this indication mean i need to fix some things to make it run more rich.....or does this mean i need a new O2 sensor? I have no clue what the 411 code is all about. The car seems to be running fine but i hate seeing that check engine light on. All help is much appreciated. |
