02 S60 ECM-1600 Boost pressure sensor ECM-1300 MAF ?

.

The engine chocks and stops (as if gas tank was drying out) but would eventually restarts.

I get;
ECM-1300 Mass air flow too low
ECM-1600 boost pressure sensor - Signal too low
ECM-170F boost pressure sensor - Faulty signal

Beside wiring / electrical short circuits etc problems, the common denominator explanation in Vida is is a defective boost sensor.

Most other threads and websites show either of these sensors. See pictures please
Which one are we talking about?

Can I check / test any of these with a Multimeter or something?

I hate to buy 3 sensors, 2 boost and one MAF, when only one may be needed.

thank you

The top one is located clipped to the air cleaner box and is not a boost pressure sensor; it's a TCV (turbo control valve)

The lower picture is the BPS and is Iocated on the intercooler pipe leading to the throttle body.

If resetting the engine code doesn't clear or it returns it should be replaced. Junkyards will sell this cheaply enough.
