DTC DESCRIPTION P0390 - CAMSHAFT POSITION SENSOR B CIRCUIT (BANK 2)

Description:	This DTC sets when the CMP21 (6.2L) or CMP22 (all others) circuit signal can not be detected. For additional camshaft position (CMP) sensor location information, refer to ENGINE CONTROL COMPONENTS .
Possible Causes:	CMP21 circuit open (6.2L) CMP22 circuit open (all others) CMP21 circuit short to ground (6.2L) CMP22 circuit short to ground (all others) CMP21 circuit short to voltage (6.2L) CMP22 circuit short to voltage (all others) SIGRTN circuit open CMP21 circuit shorted to other CMP circuits (6.2L) CMP22 circuit shorted to other CMP circuits (all others) Camshaft timing incorrectly set Camshaft position sensor trigger wheel out of alignment Damaged camshaft position bank 2 sensor 1 (CMP21) shielding (6.2L) Damaged camshaft position bank 2 sensor 2 (CMP22) shielding (all others) CMP21 sensor incorrectly installed (6.2L) CMP22 sensor incorrectly installed (all others) Continuous oil flow to the VCT piston chamber Erratic camshaft position due to low oil pressure Oil flow restriction in the oil passages or the VCT valve body Damaged CMP21 sensor (6.2L) Damaged CMP22 sensor (all others)
Diagnostic Aids:	Harness routing, harness alterations, incorrect shielding, or electrical interference from other systems may have an intermittent impact on the CMP signal. Diagnose any base engine concerns related to the engine oil pressure or engine timing. Refer to the Engine System General Information article, Oil Pressure Test, to check the engine oil pressure. Refer to the Engine article to check the engine timing and VCT phasers.
