ecu light

Is the ECU light in the floorboard of the passenger side of the car supposed to blink when nothing is wrong? Its just one flash every 5 sec or so so i dont think its putting out a code, but I just wanted to make sure

it's just letting you know it's working (hmm, at least i seem to remember mine blinking like that).

the only time you have to worry about an error code is if your check engine light comes on.

check the 4th gen site for more info on error codes :D

nah man, that means the O2 sensor is shot, it should blink once at initial start up and then none afterwards.... and code one is O2

how can I check my O2 sensor to see if it is shot?
