Actually OBD1 started on 1980
OBD2 started 1988 up to present, ... check the posts * OBD 2 by yours truly...

About the importance of O2 sensor... completely retarded nga kaya ang manufacturer ng 1997 Lancer GLXi, dahil walang equipped na 02 sensor yung vehicle na nirelease nila??.... and from your point of view (OBD-TWO *1997-Present*) pasok sya dyan???

Little knowledge is dangerous.... Peace pa rin!!!
