PCM sets DTC P0236 when the between Boost Pressure Sensor (BPS) and atmospheric pressure have a gap under the engine stop condition.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Plausibility check | 1. Poor connector connection 2. Leakage on surge tank 3. Leakage on intercooler 4. Defected Boost Pressure Sensor (BPS) 5. Defected Manifold Absoulte Pressure Sensor (MAPS) 6. Defected Barometric Pressure Sensor |
Enable Conditions |
•
More than 4 sec. after engine "OFF"
•
The boost pressure sensor voltage is at between 0.16V and 4.92V
•
The MAP sensor voltage is at between 0.15V and 4.85V | |
Threshold Value |
•
3 preconditions under the engine stop
•
Difference between boost pressure and MAP(manifold air pressure) is higher than 10KPa
•
Difference between boost pressure and AMP(atmosphere pressure) is higher than 10KPa
•
Difference between atmosphere pressure and MAP(manifold air pressure) is lower than 10KPa | |
