Well usually a error code and CEL light will come with a MAP sensor problem. Lack of power...
P0234 (M) Turbo Boost Limit Exceeded Problem detected in turbocharger wastegate.
P0236 (M) Map Sensor Too High Too Long Problem detected in turbocharger wastegate.
P0237 (M) Map Sensor Voltage Too Low MAP sensor voltage input below the minimum acceptable voltage.
P0238 (M) Map Sensor Voltage Too High MAP sensor voltage input above the maximum acceptable voltage.
Well the best way to find out if the MAP sensor is to use a Live Data Scanner... Something that allows you to see the actual boost pressure value from the sensor. I would suggest ScanGauge II but I know it doesn't report the right value...:bang:
