P0140 After Piggies

[DylanFulton]

Tackled the job of Piggie pipes over the weekend, all went well (pretty much). I've had my CEL come on with P0140 "02 sensor CKT no activity (bank 1 sensor 2)". I've done some searching and haven't come up with a solid answer. Not sure if it may be the spacers I used (can't remember brand, got them off of Amazon) or if my 02 sensor just coincidentally crapped out. Any ideas?

On the plus side, piggies and an x-pipe is a good, inexpensive mod for some bangin' sound.

Did you check to see if the O2 sensors needed to be re-positioned?

Yes the sensors are sitting in properly

kind of out of topic, but what x-pipe?
Im getting the piggies soon, and think Im just going FI catback too..

Spacers don't always work from what I've read. JHM tune will code O2 sensors out and also pass emissions.

I'm doing my piggies tomorrow; already have a spare set gutted and ready. How long did it take to remove yours?

Just bought a 2.5" generic x-pipe from an exhaust shop. Had to use some adapters to make it fit, all in all it was about $100 in parts. I had a friend of mine weld it in so labor was only a 6 pack.

I think it may be the spacers I used, it's just strange that it's only one side. It took me about 20 mins to gut each cat. The removal of the exhaust is another story
