DTC P0236-00: Boost Pressure Sensor Circuit Range/Performance Problem: Notes

DTC P0236:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0236:00 Boost pressure sensor circuit range/performance problem
DETECTION CONDITION
  • Any one of the following conditions is met:
    • The condition has continued for 1 s in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is more than 12.0 kPa {0.122 kgf/cm2 , 1.74 psi}, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is more than 13.3 kPa {0.136 kgf/cm2 , 1.93 psi} and difference in turbocharger/supercharger boost pressure and exhaust pressure is less than -30.7 kPa {-0.313 kgf/cm2 , -4.45 psi}.
      • The condition has continued for 1 s in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is less than - 12.0 kPa {-0.122 kgf/cm2 , -1.74 psi}, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is less than -13.3 kPa {-0.136 kgf/cm2 , -1.93 psi} and difference in turbocharger/supercharger boost pressure and exhaust pressure is more than 30.7 kPa {0.313 kgf/cm2 , 4.45 psi}.

MONITORING CONDITIONS
  • Ignition switched OFF: 12.0-15.0 min have elapsed
  • The following DTCs are not detected:
    • BARO sensor: P2228:00, P2229:00
    • MAP sensor: P0107:00, P0108:00
    • Boost pressure sensor: P0237:00, P0238:00
      • Exhaust gas pressure sensor: P0472:00, P0473:00

Diagnostic support note
  • This is a continuous monitor (CCM).
  • The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.
  • PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle.
  • FREEZE FRAME DATA/Snapshot data is available.
  • DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION
  • Not applicable
POSSIBLE CAUSE
  • Boost pressure sensor/boost air temperature sensor connector or terminals malfunction
  • Boost pressure sensor malfunction
  • PCM connector or terminals malfunction
  • PCM malfunction
SYSTEM WIRING DIAGRAM
  • Not applicable
