DTC P0238: Turbocharger/Supercharger Boost Sensor A Circuit High

P0238 - TURBOCHARGER/SUPERCHARGER BOOST SENSOR A CIRCUIT HIGH

Description:  The powertrain control module (PCM) continuously monitors the TCBP circuit for concerns. This DTC sets when the PCM detects an open circuit or high voltage in the circuit.
Possible Causes: 
  • Damaged turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor
  • TCBP circuit open or short to voltage
Diagnostic Aids:  Check the harness for intermittent concerns, incorrect connections, routing, alterations and damage due to contact with other components.
The TCBP/CACT sensor is a dual function pressure and temperature sensor located on the intake air tube between the charge air cooler (CAC) and the throttle body.
