Is this the airflow meter and throttle housing and tps switch all combined in one unit ?

If it is it can be repaired , where the tin cover is siliconed sealed on the side, cut round it with a blade ( use appropriate saftey gear , googles , saftey gloves ..health and safety and all that )

When you have removed the cover there are if i remember correctly 3 soldered joints, they are the supply and earth to the air mass, you will see where the solder has burned away from the connector leg, just re solder.

A have done a few of these but it was a good few years ago so its from memory.
