The check engine light (CEL) in your WRX is a warning sign that something is wrong with the engine or the emissions system. When the CEL flashes, it usually indicates a severe problem that can cause damage to the engine or emissions system. You should immediately pull over and turn off the engine to prevent further damage.
Some of the common reasons why your WRX check engine light may be flashing include:
- Ignition misfire

You can use an OBD2 scanner to check the error codes and diagnose the problem. However, we recommend taking your WRX to a certified mechanic to avoid any further damage or complications.
Why is your WRX cruise control disabled when the check engine light is flashing?

Therefore, it is important to immediately turn off cruise control when you notice the CEL flashing. Once the problem is fixed, you can turn on the cruise control again.
