Incredible 2005 Subaru Outback Check Engine Light Cruise References. I've been told by a subaru mechanic that both these symptoms are likely caused by a failed front o2 sensor. Web check engine light means code is stored, the check engine light disables the cruise control so you will take your car into get it fixed.

Find out what the trouble code was rather than the description. Issue has been occuring for the past month, it worked again by itself for a week but problem came back. And yes, i know i should fix the cel issue, but aside from that.
