Pull your rears, swap the plugs and you should be good to go, I just did mine this way, works great. My tune finally paid for itself with what I saved on the new O2's

 

Ya I just priced the damn things. You just spliced the wires?

 

I am wondering about this too.... I stripped the front passenger side 02 sensor threads while putting my long tube headers on. I have my rear 02 sensors shut off and I wanted to switch the plugs but wasnt sure on the wires. Is there 4 wires on each? The rear ones are labeled a,b,c etc. Any info would help. THANKS IN ADVANCE

 

The front ones are labeled too. I just took the keeper off the plug, and pushed the connector out and swapped the plugs. I had planned on splicing them but didnt need to.

 

im throwing two codes and one is the passenger side precat and the post cats are tuned out. can i just switch them postcat to precat? The other code is "low input to bank 1 sensor 1" I dont mean to steal anothers thread but any ideas?

 

I am going to try to find time to do this today! If I get really into I will do a write up in it.

I guess if you can put the rears in the front you can put the front in the rears. I will try yo look at both, possibly today.

I will keep you all posted.

 

OK, that was too easy! I got both sides done in a half hour. Got too into it to take any pics. I have not logged any thing yet, but the truck runs!

 

Well I swapped out the fronts with the rears. Now I have NO 02 action at all! !@%#? I just replaced the connectors and swapped them out. Took about 1/2 an hour for all four senors. I now have new sets of codes and I think I might have to break down and just get some new ones! Any one have any laying around or some money I could have?!

 

OK, I am getting codes:
P0134: 02S Circuit Insufficant Activity Bank1 Sensor1
P0155: 02S Heater Performance Bank2 Sensor1
I am using EFILive v7.3 and it shows the sensors voltage for both Bank1 and Bank2 for sensor 1 , but I can't get anything to read for long fuel trim Bank1 and Bank2.
What is Bank and what is Sensor? So like, Bank1 Sensor1 is what, Driver's front?

I had Allen turn off my rears if this helps any.

 

damn, my rears work(ed) great up front. Are all the connections good. Did any wires pull out off the connector?
