1997 Toyota Rav 4 Engine Check light sensor and how to check diagnostics codes
Hello my girl friends Toyota check light will come on every once in a while then stay off for weeks so I was wondering is the check light a sensor that could be dirty? Whatever the problem is it's minor so if anyone know's if it's just a sensor and where it's located I can just get to it and clean it up. Some sensors on engines will short out after a few years from carbon build up, dirt, oil, ect. So it's always good to take them out once in a while and clean it with a degreaser. And I know it works for mustangs but can you take a paper clip into one of the holes of the computer to get a diagnostic code read out from the dash lights?
If someone has any information on that please let me know on here.
Thank you.
