Does anyone know if I should just replace all four sensors and this should solve the problem, i have 78K miles. Or is it something else that is triggering the SES light? Any one have these codes and what was the fix?
Thanks in advance!
Changing O2 sensors won't solve anything. I would check for air leaks, cracked air boot or vaccum lines, maybe a torn OS hose.
