Ferrari oxygen sensor Videos

If your cat would not work properly anymore, what would that do on CO and O2 emissions when you are checking an O2 sensor with gas emission tests? Picturing myself the place of the O2 and what it's measuring (O2) and what your gas tester is measuring (after the cat did it's magical hussle on the gasses to CREATE the output you read). If the cat is left out due to a defect and you would go for a gas test, could you have wrong assumptions on how well an O2 is doing it's job? This would not be an actual false or lean (since it is behind the sensor) but still makes the test obsolete. Also in the last picture (bad airpump) you do state that after pinching the hose, you have rich conditions (block learn and integrator below 128), as a result of contaminated oil (extra fuel vapor entering combustion proces via PCV I guess). How come there is still 1% O2 on emission, that would indicate lean still, since 0% is stoiomatric? Or is this a catalic thing and should you read O2 sensor for real condition only (my guess, always go to the source, don't use reactions further down the line).

Is this crank position sensor the same as the Neutral Safety Sensor? On the other hand, when the crank position sensor fails, does the starter motor also fails? Sometimes I have a problem with the starter motor and need to wait for about 15 minutes in order the motor cools down so the starter motor works again. I´ll appreciate your comments. Thanks

@Mordaan Thanks, mine is doing something similar, but not that bad. I was thinking that it could be one of these 2 sensors (cam/crank) but unsure, as it could also be coils, lamba, temp sensor. I hate electronics. Anyway, thanks for the vid, I'm now leaning towards the CPS.

EGR problem?

It could be air flow meter ( MAF ). You should check it.
