Just replaced my vacuum pump. To do so, I unplugged the camshaft sensor and manually turned the cam to remove and install the belt for the vacuum pump. Put it all back together, topped off with oil. Now when I start it, it has a delayed start and throws codes. Once it runs, it's fine and you'd never know anything was wrong. Just the delayed start (aka, takes a few seconds longer with the key turned).

I did have an issue getting the sensor connector apart. It was so brittle, I broke the little red lock just sliding it off. However, I got it all put together and zip tied it so it doesn't come loose. I encountered this issue a few weeks ago and am just stumped with what could be wrong and how to fix it.

Codes being thrown:
P0340 - Intake Camshaft Position Sensor Circuit
P06DA - Engine Oil Pressure Control Solenoid Valve Control Circuit
