My reference shows 2004-2008 as being similar for the Vibe. Some minor changes occur from year to year as from model to model, but the basic procedure for this remains the same in those model years.

The new PCM on these has to be programmed either by the people that built it or by someone who has the capability to reprogram it [usually a dealership]. The computer can be programmed before it is installed and usually they'll need the VIN#, mileage, etc to do this properly. I don't believe the vehicle will run if you put in an unprogrammed PCM. It's very rare for one of these PCM's to fail so make sure that you haven't overlooked some other problem that is mimicing a bad ECM before ordering one as they are quite expensive.

its not the battery its still cranking isnt it! Probably needs an ecm. By the way it will say Toyota right on it so the toyota version has the same dang problem!!!!

we had the computer code p2716 on our 2005 pontiac vibe -shift solenoid. gm says to replace the pcm before you do anything else.  we tried this and it works.
