Hey all,

I did change the oil pressure switch on my 150 FICHT...right away I got a new check engine alarm. Initially I thought it was because I started the engine with the air temperature sensor disconnected, however after connecting it the alarm is still coming ON every time. I will get the code tomorrow. One question, could it be air in the oil system? How do I vent the air out of the oil loop after replacing the pressure switch?

Cheers,
Pedro
