OK here we go, My car was fine until I powerwashed the motor today and now all of a sudden my low oil level light keeps coming on even after I reset it. I have checked the oil level and the oil is full. and code p1416 is Air System bank 2. Is air system bank 2 the O2 sensor or what else is involved with bank 2. Is Bank 2 is the passenger side or driver? where is the oil level sensor located and will this go away after the motor dries or did I damage this sensor.

 

Anyone?

 

bank 2 is the right.check to make sure you didn't knock the hose off the check valve behind the left head[secondary air-bank 2].the oil level sensor is in the oil pan[i think right side].it'snot reccomended to power wash the motor[any late model]

 

No the hose is connected, could it be the O2 sensor. I just recently took off the stock exhaust manifold and replaced them with a set of Hooker Shorties. but that was a week ago and the car ran fine until I washed all the dust out of the engine bay.

 

no.the o2 is working[that's how the pcm knows secondary air.when secondary air comes on the voltage has to go real low,which means the more oxygen in the exhaust.] more than likely the check valve puked.

 

Well the good news is I reset this code and my low oil level on the DIC has also stopped from appearing. I just let the motor dry all day and just took it for a 35 minute drive and everything is back to normal. "Lesson for the day" Don't power wash the motor.
