I have the 02A CEL code. which o2 sensor is this?
So my check engine light came on not too long ago and I used this https://honda-tech.com/forums/honda-civic-del-sol-1992-2000-1/how-pull-cel-d4-srs-abs-codes-code-lists-1901557/ to figure out the code. it was just a short flash so according to that link it is the O2A oxygen sensor #1. Is that the o2 sensor in the header or the exhaust?
