How does changing your bellos create 34 and 48 codes (ses). Is there a way to check, via volt meter, if your MAF has broken during the install. I swear the MAF was set down gently? But maybe I broke the MAP sensor? How do you check the MAP sensor?

Its sort of hard to rationalize your codes against the data.

Appears DTC 48 is not an "active" code, just a stored one. Possibly you forgot to connect the MAF sensor, then connected it? The AFGS shows 10.4, so appears to be reading correctly for your cold start condition.

MAP on the other hand is a problem. Appears is was able to successfully record the barometric pressure (99.7 kPa), but now it is showing 10.7 kPa MAP at idle, which is why you have an "active" code for MAP. At idle it will normally read 30-35 kPa, and a reading significantly below that sets the low voltage/high vacuum code. There is simply no way the engine can run at that MAP value, which would correspond to about 27"Hg vacuum. Indicates the sensor may be bad, but odd that it set the barometric pressure correctly. Check the harness connector. They are known to dry out and crumble with age, giving you faulty readings, but mostly on an intermittent basis.

You can use something like a Mit-E-Vac to pull a vacuum on the MAP sensor, with it still connected to the harness, and measure the output voltage. I can give you the correct readings if you need them.
