What is the code for????????? E.G. engine management/ABS/Airbag etc etc! Then i will be able to tell u!! :)

And carina oxy sensor by the way is code 21!! ;)

From Haynes manual for US 4A-FE/7A-FE... I assume European is the same, since it predates OBD-II: Code 24: Intake air temperature sensor: open or short in IAT sensor circuit
