Toyota Repair: engine light, diagnostic fee, scantool

Question
My 2001 toyota tacaoma engine light came on. what steps should i take?

Answer
The first step is to retrieve the diagnostic code by connecting a diagnostic scantool, this will indicate what component or circuit may be causing the malfunction, some of the major auto chain stores such as autozone will do this at no charge, the dealer and most repair shops will charge a diagnostic fee of around $90.When the trouble codes are known you can follow up and let me know and I can then help.
