I would like to know the location of the mass air flow sensor, the engine is a B5S5F_20V, non-turbo.

I had it at the volov dealer, fault codes are TCM222, ECM 121, 214

Needs CMP, MAF, RPM sensors,

What is the CMP sensor?

I would like to start replacing the sensors, starting with teh MAF but I do not know where it is located?
