DTC P0236: Turbocharger/Supercharger Boost Sensor A Circuit Range/Performance

P0236 - TURBOCHARGER/SUPERCHARGER BOOST SENSOR A CIRCUIT RANGE/PERFORMANCE

Description: This DTC sets when either of the following conditions are present. When the throttle intake pressure (TIP_PRS_BOOST) PID does not correlate with the barometric pressure (BARO) and the manifold absolute pressure (MAP) PIDs at ignition ON. When the turbocharger boost pressure (TCBP) sensor does not correlate with the BARO sensor at idle and the TCBP sensor and MAP sensor fail to correlate while driving.
Possible Causes: Damaged turbocharger boost pressure (TCBP)/charge air cooler temperature (CACT) sensor Contaminated or blocked TCBP/CACT sensor Slow responding TCBP/CACT sensor
Diagnostic Aids: Check the intake air system for leaks and restrictions. 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.
