Resistor in map sensor now throwing p0237

While changing glow plugs today I unplugged the map sensor and found a resistor between 2 of the poles. When I reconnected the plug the trucl through a check engine light and my insight cts shows a p0237 code. The truck also has laggy throttle response and never shows more than about 7lbs of boost. I have tried removing the resistor and it didnt help. What did I do?

the turbo code can be caused by the map apparently

I think you didn't get something back together properly ?
as far as the resistor here is an old thread about what it does

This resistor was in the map sensor plug. Not the icp sensor. Is it supposed to work like a boost fooler? Everything is plugged in

sorry wrong thread // yes it should just be a boost fooler and since you removed it and tried that ,, IDK whats up with your turbo code?
