i have an air fuel gauge ....well i was driving home a few minutes ago and it was barely working ..only lean was lighting up and i floored it and then the check engine light came on ..when i let off on the gas the check engine light shut off . so i check all my connections , i unplus the o2 sensor and a metal terminal falls out . so basically the connector is no good . what i wanna know is can i just bypass the connector and just solder the wires together ?

 

yes

 

Replace it with a universal plug from an autoparts store or just use insulated spade connectors. You'll regret soldering it if you ever have to take it off (e.g. exhaust work).

 

spade connectors it is ...i have some in my garage .
