I got my Y isntalled a week before my check engine light came on

i diagnosed it and i got
0302 and 0304
0304 - knock sensor

0302-
- The electrical harness or connectors (valve circuit open or shorted)
- The EGR valve is stuck closed
- Weak or dead battery
- The EGR passage is clogged
- Faulty EGR temperature sensor circuit
- A leak somewhere in the exhaust system

I Was wondering if any of you got these CODES???

No problems here.

They are common, reset and see if they come back. Oh, and you'll get a better 4th gen response in the 4th gen forum.

but the only code i'm getting says i got 3 bad O2 sensors.
replace 2 of 3 02's and it STILL says i got 3 bad O2 sensors.
