Subaru Check Engine Light On and Cruise Control Flashing: A Comprehensive Guide
As I was cruising down the highway with my trusty Subaru Outback, I noticed something peculiar. The dreaded check engine light flickered on, accompanied by the incessant flashing of the cruise control indicator. My heart sank as a wave of panic washed over me. What could this ominous combination mean?
Determined to unravel the mystery, I pulled over to the side of the road and consulted my trusty Haynes manual. To my dismay, the manual offered little solace, leaving me none the wiser about the cause of the issue. Undeterred, I reached for my laptop and began scouring the vast expanse of the internet for answers.
Diagnosing the Check Engine Light and Cruise Control Flashing
After hours of diligent investigation, I discovered that the check engine light and flashing cruise control indicator are often indicative of a problem with the vehicle’s engine control system. This system, also known as the engine management system (EMS), is responsible for regulating various aspects of the engine’s operation, including fuel injection, ignition timing, and emissions control.
When the EMS detects an issue, it triggers the check engine light to illuminate. The flashing cruise control indicator is often a secondary symptom, indicating that the EMS has disabled the cruise control function as a safety precaution.

Numerous factors can trigger the check engine light and cruise control flashing, including:
- Faulty oxygen sensors
