Quick question from my semi-uneducated self, is it safe to run my car without the O2 sensor hooked up?

I ordered a new ZZP downpipe which should be arriving on Monday, however I got an email saying they ran out of O2 extension harnesses and won't have any for approximately 2 weeks. And then it'll still have to be shipped to me.

It's not a problem if I have to wait, but I'd just rather not have box of new parts sitting there unable to be installed.

 

Iirc the secondary o2 sensor can reach the o2 bung in the zzp unit.

But your car will not like things without a secondary o2, if the wiring can't reach just leave the stock one on for the extra week or two.

Alright I'll just wait then. I figured that's what would end up happening.

Thanks!

 

if u have hptuners u can just turn off the codes for the secondary o2, I have mine totally removed.

 

Your car will be fine without the 2nd O_2 sensor. The car doesnt use the info from that sensor for anything related to A/F. Its for emmissions only. You will have a code until the sensor is replaced but the car should run.
