8= o2 sensor codes same time?
Hey guys,
Im trying to figure out why im getting codes 161,132,138,152,158,135,141,155 at the same time. They are all related to banks 1 and 2 o2 sensor and the o2 heater banks 1,2 for the o2
.Ive erased them twice, only to have all these 8 come right back after start up!!
Im thinking a short? no blown fuses found so far. Are there any inline fuses on the wiring harness?
I just got my scan tool back today from a warranty claim to find this out, so I havn't messed with it much yet. Its seems like a ground in the o2 system or wiring of some sorts is my first guess here. Im planning on tackling this weekend if my parts come in. I ordered new sensors just in case 4 total. 2 front and 2 rear.
Looking for any ideas tips before I tackle this..I get a higher rpms start up than it use to. Its hitting 2200+ where a month ago and beyond the initial start up rpm would hit roughly 1600 and then drop down..its getting crappy fuel economy as well..
Any and all Ideas welcome at this point. Im trying to do all the research I can before I dig in.
It has 81,000 miles 4.7 auto. 2008 slt
Also planning to replace all the plugs as well..
Thoughts?
Thanks

Only thing I could additionally think of is a mal-adjusted throttle position sensor if it has one. If it isn't adjusted right some funky things can happen. And if it is good but not adjusted then I don't think you would get TPS codes. Only O2 saying lean or rich. It would also not run optimally.
