Can anyone tell me if the o2 sensor on an 89 560sel has its own indicator light on the dash or is it the check engine light? Im trying to figure out if all my dash indicator lights are working as they should. Thanks Tom

Hey Tom,

If the O2 sensor fails it can kick on the "check engine" light. (There isn't a separate one for the O2 sensor.)


cheers

Ok , Thanks for your help. Tom
