P0236-00: (PCM - VIN Y) DETECTION CONDITION AND POSSIBLE CAUSE

System malfunction location Boost pressure sensor circuit range/performance problem
Detection condition
  • Any one of the following conditions is met:
    • The condition has continued in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is standard or more, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or more and difference in turbocharger/supercharger boost pressure and exhaust pressure is standard or less.
    • The condition has continued in which difference in barometric pressure measured and turbocharger/supercharger boost pressure is standard or less, difference in manifold absolute pressure and turbocharger/supercharger boost pressure is standard or less and difference in turbocharger/supercharger boost pressure and exhaust pressure is standard or more.

Precondition 
  • Ignition switched off: 12.0-15.0 min have elapsed
  • The following DTCs are not detected:
    • BARO sensor: P2228:00 and P2229:00
    • MAP sensor: P0107:00 and P0108:00
    • Boost pressure sensor: P0237:00 and P0238:00
    • Exhaust gas pressure sensor: P0472:00 and P0473:00
Fail-safe
  • Not applicable
Possible cause
  1. Boost pressure sensor connector or terminals malfunction (see CLEARING DTC .)
  2. Boost pressure sensor malfunction (Refer to applicable BOOST PRESSURE SENSOR INSPECTION (VIN Y) in the service information.)
  3. PCM connector or terminals malfunction (see CLEARING DTC .)
  4. PCM malfunction (Refer to applicable PCM REMOVAL/INSTALLATION (VIN Y) in the service information.)
Repeatability verification procedure
  1. Clear the DTC recorded in the memory. (see CLEARING DTC .)
  2. Replicate the vehicle conditions at the time the DTC was detected using the following procedure.
    • Start the engine. (Engine cold)
    • Drive the vehicle on a flat road surface 10 times under the following conditions.
    1. Drive the vehicle in second gear at 25 km/h {16 mph} while maintaining the speed for 25 s.
    2. Stop the vehicle and idle the engine.
  3. Perform the DTC inspection for the PCM. (See DTC INSPECTION .)
