So.. before you guys flame me.. yes i checked the forum, and no its not solving my problems no matter what i try.

Codes:
P0159-Rear O2S, Bank 2
P1166-Heated O2 Sensor 2
P1147-Heated O2 Sensor 2
P1167-Heated O2 Sensor 2

Story:
got Megan testpipes. check engine light. got o2 spacers. still throwing codes. tried all combinations. even tried the one CEL delete that was posted on here. Once i got the o2 spacers in.. my car decided to throw even MORE codes. and i dont know how to get rid of them.. should i get new o2 sensors as a whole? or should i try a certain combination of o2 spacers? i have the elbow ones from ebay.


VDC & Slip lights:
Yes i searched for it, and yes i got my answer. I swapped out the camshaft position sensors and it fixed my issue. But now they only come on whenever i hit a hard bump. JUST a hard bump. then i searched for it again.. they say low brake fluid.. so i topped it off and it STILL comes on. then i searched once again, they say low brake pads. but i upgraded my brakes to the akebono 370z brakes and my brake pads virtually have maybe 3k miles on them. so that cant be it either.

Any help would be greatly appreciated.. tried almost everything and cant figure it out. i searched this forum page for answers and tried every method there was listed here.

i put pictures down below to show you codes

 

no one has an answer for me?! ((

 

I'm in the same boat. I'm getting the P1147 now (used to get p0430). Megan test pipes with 2x o2 spacers.

The 1147 is what I'm curious about. Right before it came on, I hit the throttle hard and it hesitated slightly. After the power seemed to be down and the exhaust was rattling much more than usual.

Do any rear o2 codes like this (P1147) affect engine operation?

 

Normally, the rear o2 sensors only monitors if you have cat converter.

But, I had one of the rear ones short out for some reason and it effected my drive-ability. With my scan tool, the voltage on that one bad was way out of range. I think it shorting out affected the voltage of ecu or other o2 sensors?? My car would hesitate pretty bad.

I bought another rear sensor used one from the junkyard, now its fine lol.
