system readiness fail
Well find out the actual code being triggered, then fix the issue:
P0138 1/2 O2S Shorted To Voltage
P0141 1/2 02 Sens Relay
Sounds like the relay is to blame. Swap the relay with one of the same number like the horn and see if it goes away, if it does replace the relay.
If not, the check the harness ar the O2 sensor or replace it with a Desno or NTK O2 senor.

hydra i checked the relay which is also the asd relay as well looked fine sprayed it with electronic cleaner and it is working fine, i did get one from napa but i dont trust it. also the chk eng light has been off for a couple of days now but when the weather breaks im gona change the o2 sensor, i got it in the glove box.
