If abnormal atmosphere pressure is detected, the PCM sets DTC P2227.
Item | Detecting Condition | Possible Cause | |
DTC Strategy |
•
Plausibility check | 1. Poor Connector Connection 2. Misadjust crankshaft and camshaft pulley position | |
Enable Condition | Case 1 |
•
More than 4 sec. after engine "OFF"
•
Atmosphere pressure sensor voltage is at between 0.16V and 4.92V
•
Boost pressure sensor voltage is at between 0.13V and 4.95V
•
MAP sensor voltage is at between 0.15V and 4.85V | |
Case 2 |
•
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 | ||
