I have a Toyota RAV4 2002 4WD.
I was driving to the car wash when suddenly the check engine light come on when I accelerated hard. After the wash, it still was on. I drove home, shut it off, turn it back on, light still on. Went and got my scan tool, pluged it in and fired up the engine and now the light suddenly went away.
I know these models have problems with Air/fuel sensors, O2 sensors and ECUs.
Can something have happend to my ECU? Or is this "normal"? I can still see live data, and the light has not come on again. Everything seems to be normal. There are no stored codes in the ECU either.
I am using a Bluetooth OBD-II reader and the Torque app.
