So after 80k miles I am having first problem with my ss. Couple of days ago I had to remove air box. And when putting everything back I forgot to conect map sensor. Drove couple of miles and check engine light went on. I stopped and conected map sensor back. Than disconnected the battery to reset the ecm and light went away. Then yesterday it came back. I stopped at AutoZone and they pulled the code p2261. Which is for BOV stuck closed. The car still runs fine,producing 20+psi. So any idea what I should do next? Thanks in advance.

 

Do you have a BOV? Or the stock BPV? Check for vacuum leaks, especially around the bypass solenoid and the vacuum tank.

 

Just a FYI.
MAF sensor (not MAP) is the one on the air filter housing.
Our SS's don't have a BOV. They have a BPV (bypass valve)

I would try clearing the codes again. If it comes back with the same number, then check the vacuum connections for the BPV.
Last would be to pull the BPV cover and check the spring and rubber diaphram.
Just 3 small bolts to remove the cover.

 

I have z54 turbo from zzp. I think it has same BOV as stock one. But I thought maybe this problem has something to do with me not connecting maf sensor.

 

sorry. Sometimes I am confused about parts names.

 

Have a read thru this, there are several probable causes

If you're running an aftermarket turbo, sorry but I'm not up on the tech for those. You can try what I suggested (if it applies to your z54).

 

I’m thinking loose wires from the air filter box remove and replace. Maybe a bent pin.

 

Maybe if we knew why you had to remove the airbox, we could narrow down the possible causes.

 

Went outside. Checked all the wires and connectors. Couldn't find anything loose. But notice that little black part has one nipple without any hose connected to it.
