DTC P025E: TURBOCHARGER/SUPERCHARGER BOOST SENSOR A INTERMITTENT/ERRATIC

Description:  The powertrain control module (PCM) continuously monitors the TCBP circuit for concerns.
The test fails when the PCM detects ten intermittent events during a single drive cycle.
Possible Causes: 
  • Damaged turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor
  • Damaged harness connector
  • Damaged harness
Diagnostic Aids:  Check the harness for intermittent concerns, poor connection, 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.
