Have Toyota Questions? Ask a Mechanic for Answers ASAP
Thanks for posting
The check engine light turning on will cause the vsc system to be disabled and that's why that light is on, we need to get some diagnostic information in order to help, there are some codes in the car's computer, most autoparts stores like autozone, O Reilly can help you get the trouble codes(except in CA) they offer this at no charge, please see if you can do this and then let me know the diagnostic codes (DTCs) they record for you, I would also like a model description, what model AWD is it? And engine size, 4 cyl, V6, V8? Thank you.
That would be geat , thanks.
Thanks , that's kind of a common problem, it sounds like the problem may be a vacuum leak since you are getting whistling noise as well, I have encountered this code many times and this is the first time I have ever seen it being diagnosed as a fuel pump gasket, could be a generic explanation but not specific to Toyota. The most common problems for this code are a vacuum hose disconnect under the hood or a hose disconnected or damaged for the fuel vapor recovery system, or even more common the mass airflow sensor (MAF0 sensor, it is located in the air intake duct between the air filter and the throttle body.
