First up,reset the ECU and clear these error codes by disconnecting the negative battery terminal for a minute or two.Then recheck the error codes to make sure the codes were cleared properly,it should give a continuous code 12 once its cleared.Then after the car has been driven for half an hour or so,recheck the error codes again to see if any of them are current and have set an error code again.Sometimes error codes can set from a one off "glitch" in the system,so clearing them,driving the car,and rechecking the error codes again will confirm if there is a problem somewhere.If the error codes dont show up again after driving the car for half an hour or so,its best to recheck the error codes again a few times over the next few days to make sure it hasnt set an error code again later on..
