I was wondering. If I bought an o2 sim would it be ok to run with the secondary o2 unplugged? I mean the o2 sim is supposed to send false readings to the ecu to imitate a perfectly fine secondary o2 sensor right? I'm asking because my secondary o2 sensor broke and I was wondering if I could get away with just buying an o2 sim to get rid of the passive CEL that I'm getting with my secondary o2 unplugged
