P1151 Code!!
Ok guys so today my CEL Came on, it threw the Code P1151 - lack of H02s21 switches..sensor indicates lean.
I installed my diablo tune 2 days ago, and put my O/r Mid pipe on 3 days ago... could this have anythin to do with it?
If not where do i start?

RE: P1151 Code!!
im sorry i dont know if O/r meens on or off road but if you have off road x pipe then you need to delete the rear 02's with your tuner. that should fix that. if you have on road then someone else will have to help you with that, cause i think a number of things can cause that [&:]

MIL elims or turning the rear o2s off isn't gonna fix your problem.
H02s21 broken down:
Ho2s = heater o2 sensor
2 = Bank 2 (Passenger side)
1 = Sensor 1 (front)
Sounds like you may have a bad sensor, bad connection, or possibly an easy fix if you're lucky (bad injector, dirty MAF)...
