more fault codes , can someone help me please

[spudboy6]

so my codes are

00525 -G39 - 02 sensor , i know to change the lamba on this
00519- intake manifold pressure sensor -G71 signal too low ? what do i do
00625- vehicle speed sensor signal not plausable ? what do i do
00588- airbag igniter drivers side N95 ressistance too high


im mainly worried about this speed signal sensor and manifold pressure sensopr , if anyone could help me please i would be ever so thankfull ,

MAP sensor is with the ECU, there's a piece of vacuum pipe going to it that perishes and leaks. Have a check see if there's a leak.

Do these vaccum pipes actually join to the ecu ? And is map sensor on the 1.4 AEX on the drivers side if the manifold with a 4wire plug ?

Thanks

AEX is on the manifold, its a small things that bolts directly to it,  i think it is 4 pin from memory, not many other 4 pin things bolted to the manifold anyway
