[snaimpally]

There is a garage near where I work that has done a lot of my work on my previous and current car so I know them very well. My service advisor and the manager cleared a bay and assisted me with installing the JB4.

For the first 2 sensors, TMAP and MAP, the JB4 plugs did not snap into place and we had to use cable ties to hold them in place. Is this normal? The plugs only fit in one way and I double checked, my JB4 is marked "N55 S2". The other sensors snapped in place perfectly.

After the install, the car started fine and no CELs. I went to drop something off at a friend's house. Probably drove 3-4 miles. Then when I started it up again, I got the following codes:

P0101 - Mass or Volume Air Flow Circuit Range/Performance Problem
P0237 - P0237 Turbocharger Boost Sensor A Circuit Low
P1001 - don't know what this means

I'll check all the connections again but the first 2 sensor plugs not snapping in kind of unnerved me. Any help would be most appreciated.
