eml light on code p0430

its a x type 2.1 on o4 sorry

Catalytic converter system efficiency below threshold – bank 2, means HO2 Sensor disconnected, HO2 Sensor to ECM wiring fault, HO2 Sensor heater to ECM wiring fault HO2 Sensor heater failure Upstream HO2 Sensor failure Downstream HO2 Sensor failure Catalyst failure, I expect it is the sensor needs changing, or it could be the MAF but would change the sensor first

thanks for the reply il try changing the sensor which side is bank 2, the front or back thanks

bank 2 is the left bank of the engine nearest the front of the car, the downstream are Black connectors and the upstream have grey, and I think the one you want is under the air box

Thanks for your help i will change it an see what happens.
