WASTEGATE Control Pressure Sensor
The wastegate control pressure sensor is checked for opens, short and intermittents, P1012, P1013 and P1014.

| P1012 - voltage < 0.20 V P1013 - voltage > 4.93 V P1014 - open or shorted > 10 events in a driving cycle |
The wastegate control pressure sensor reading is checked at key-up using a four-way correlation check. If the wastegate control pressure sensor reading is higher or lower than the readings of the BARO, MAP, and TIP, a P100F is set. A P1011 is set if the wastegate control pressure is greater than BARO.
