Just swapped a low mileage 3.5eco boost into my 2011 and now I am getting a Evap purge valve short to ground and all camshaft open circuit and all O2 sensors.

I figured it must be a problem in the engine harness so I swapped it out with no change. Put a new purge valve in with no change.

any ideas would be appreciated

 

Check fuse 76 in the underhood fuse box (20A) all those components run off of that fuse.

 

checked it

 

With the key on, unplug the purge valve and let me know if the green wire on pin 2 will light a test light.

 

Yes there is power at the green wire

 

If you have good power at the green wire on pin 2 at your purge valve, verified with a test light to put the circuit under load, then everything from the battery junction box to the engine harness on the power side is good. That power wires branches off and goes to all the components you listed, from there on the only thing all those components share in common is the PCM itself as they are all individually grounded by the PCM. Next I would verify that your PCM has a proper ground on the BLK/YEL wires on pins 96, 97,98, and 99 on PCM connector C1551B, all these wires go to ground G100. You'll also want to check the following PCM fuses in the under hood fuse box, fuse 53 (5A), fuse 46 (10A), fuse 26 (10A), fuse 75 (25A); also check Fuse 42 (5A) and fuse 18 (10A) in the kick panel fuse box.

 

It all checked out ok. Is it the PCM itself? I have all the controllers from another truck. What would I have to change to run that pcm?

 

It is looking like the PCM, since you have a spare on hand plug in it, clear all the codes, turn the key off, turn the key back on, and scan for codes. It should show codes for the immobilizer since that won't be programmed to your truck, but the circuit codes should be gone if the PCM is your issue.

 

Swapped the pcm and all codes are still there.

 

Could the problem be more related to the bcm? Because it is saying there is an open circuit on SRS and to advance Trac. as well.
