Recently my girlfriends 91 Integra threw a code so when I went to investigate the oil pressure light came on which has never happened before. So today I pulled the code and it was a 43, could the o2 sensor be faulty and dumping too much fuel? Would this be enough to cause a drop in oil pressure? Thanks

 

no, its unrelated to oil pressure. 02 sensor has its own code. check the basics first (if u havnt yet) my teg was throwing 43 and running like crap, it was a corroded ground was all
