Fault codes after timing belt...

[A4twin]

just did timing belt and a check engine light, vag it and i got to new fault codes:

16622 - Manifold Pressure / Boost Sensor (G31): Signal too High
P0238 - 001 - Upper Limit Exceeded - MIL ON
16490 - Manifold / Barometric Pressure Sensor (G71) / (F96):Implausible Signal
P0106 - 008 - Implausible Signal - MIL ON

car idles fine about 800 but did notice vacuum is about 15 or so, with a/c goes to about 18-19, also use to boost about 22 or so and come down to about 15-17 now it only goes to about 12 if that. any advice would help
TIA

Is the sensor on your intercooler piping close to the throttle body connected? Those sensors are delicate as well.

THank You...forgot to connect a connector/sensor to the intercooler. no more code boost now to 22, thanks again
