p0237

keep throwing a p0237 code. would this be caused by the turbo needing clean? will spit, sputter and throw out some white smoke under load when cold.. turbo spools up slow and sometimes sticks. usually only does it when its the motor is on the cool side..

Fault Code - Condition Description - Probable cause

P0237 - Turbo boost sensor A circuit low input - Circuit open, short to ground, MAP sensor

This is what I found - Hope it helps point you in the right direction.
I've read if your turbo is sticking, it may need to be cleaned. Personally, I don't have experience with that - I'm sure some here would know about it though.

i understand what the code is.. just want to know whats causing it.. pretty sure the turbo needs cleaned. is there a sensor in the turbo that could go bad or anything?

P0237 is an electrical fault for the MAP sensor. It could be the sensor or related wiring

The MAP is on the right side on top of the evaporator box. it's a 3 wire sensor with a pressure hose running to the intake manifold
