Post Cat Sensor Options


New member
Hi All,

I recently realized the car I bought has had the post cat sensor B1S2 cut. The connector is still there and everything but no hole in the exhaust pipe. I want to get rid of the CEL. What are my options for doing this? Does the car do any tuning from the post cat sensor? WIll putting one back in cause the cel to go away? I think the car has a fake cat(hollow) installed
