Question about codes/O2 sensor
The other day my service engine soon light came on so i got the code read today. The code was P1131 which was:
lack of H02S1 switches-lean (Bank 1 sensor 1)
I was told this was the upstream O2 sensor. My question is can i just clean the O2 sensor or do i need to replace it? Also, could i just clear the code at O'reilly's (where i got it read)? would that fix it? Thanks in advance for your help!
Also any tips on removing the o2 sensor would be appreciated, thanks!
