Have Toyota Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.In order to know where to begin with this repair the first thing you are going to need to do is to scan the computer system and see what the fault code and or codes are that are setting when the check engine light is coming on. If you can get this done and post back with them I will try and help you get this resolved.
Yes I am aware its a OBD i system but unfortunately with out know the code any thing I could suggest would be just guessing.
The overdrive light flashes when the system sees a fault and when this happens the computer should set a fault code.
