2006 Subaru Forester check engine light

Hi all, this is my first time posting. I just bought a 2006 Subaru forester with 130K miles. Recently, the check engine light came and at the same time the cruise control started flashing. I brought it to the mechanic who said I had a bad catalytic converter. The car seems to be running just fine and now a day later the engine light is off. Any thoughts or advice?

Your vehicle has the OBDII engine management system.

If the system detects a problem with the emission control system, it’ll turn on the Check Engine and record a diagnostic code indicating the where the problem lies.

If the problem no longer exists, the Check Engine light will turn off. But the system will store the code as a history code.


Take it to Autozone or Advance if the light comes back on. Then report the code back here. It will be in a P001 format.

Thanks for the advice.
