Code P0443

[Redog]

I fixed it but I figured I'd tell everybody what happened.

P0443 is a code for EVAC soilnoid issue.

When I had the LIMG fixed, my mech unbolted the soilnoid and just moved it over, instead of unpluging it. It doing that, one of the 2 wires broke inside the plug. It was makinging a connection only sometimes. The light would be on and then I hit a bump and it went out, and so on.

We took the plug apart, re-stripped the wire, re-crimped it, and reinstered into the plug housing. Another way to fix the problem would have been going to the junkyard and cutting one out of another car since GM doesn't stock this part.

We almost replaced the soilnoid, and we still would have had the problem. Check your plugs before replacing any thing like this

a pic of the part in question might help those searching. I have torn this motor down several times and i dont know which plug you are referring to.

I post a pic later, but it's the plug on the unit right by the intake above the TB

The dealer most likely does have a new pin for the connector. The techs might have them instead of the parts department though.
