Details of the Ford p0238 OBD Code
Ford code P0238 relates to a turbocharger boost sensor circuit high input condition.
Ford OBD code P0238 means Turbocharger Boost Sensor A Circuit High.
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage signal from the turbocharger boost sensor.
The turbocharger boost sensor measures the pressure of the intake air entering the engine and sends this information to the ECM.
When the ECM receives a high voltage signal from the sensor, it sets code P0238 to indicate a potential issue with the turbocharger boost system.
