There is a flap in the carpet of the passenger side footwell. If you lift it up you can see the error code light on the ECU blinking. Just count the number of flashes to get the code. If there is more than one code being thrown, there will be a long pause between sets of flashes. Some ECUs use long flashes to represent 10, i.e. two long flashes followed by three short flashes would mean 23.

9 blinks is the cyl sensor.

Have a look at the images attached to the opening post of this this topic. Do any of the symptoms listed occur in your car?

The light on the ECU or the check engine light?
