Answer 1

P0355 Crankshaft position (CKP) sensor circuit

Circuit A this is the 5 volt refference, P0355 mean either there is no CKP signal,either two event are occuring the 5 volts refference is shorted to ground, or the CKP itself is non operational.The leg of the 5 volt refference includes the throttle body the CKP and camshaft sensor, and the oil pressure sensor.
