It's a common problem with Scion XB's. I have the same year and the same thing happened to me. I researched it quite a bit before taking it to the shop and from what I could tell, often this is a vacuum leak. And that was exactly what is was for me.
Not typically an expensive fix other than the diagnostic fee.
These are check engine codes for a 2005 Scion XB. P0441, P0442, P0446. How do I fix these codes.
check warning lights
There are numerous warning lights for a Mazda RX8. Some of the warning lights are for engine oil, charging system, ABS, and check engine.
A flashing check engine light is an indication of a misfire.
A check engine light displaying on a Volvo V40 means maintenance is needed on the car. Check the car's instruction manuals to see each mileage checkup recommended by the manufacturer.Ê
It is important to pay attention to the warning lights in a vehicle. When the check engine lights are on, it indicates a problem, and it needs to be fixed.
take a battery cable off
If the check engine lights are on, that means that there is something wrong. A mechanic can check and tell what is wrong with the car.
You need to check your engine. The computer has detected a problem with the engine management system and the light is letting you know that is has error codes stored.
If your check engine light is blinking , that means a cylinder misfire has been detected
check the gas cap or the intake filter...
