All GO to Pinpoint Test HK.

P000B - Exhaust B Camshaft Position Slow Response Bank 1

Description: The PCM monitors and evaluates the response of the actual position on a target position change.

The setpoint and camshaft position are saved at the beginning of a setpoint change. If this change over time is large enough (gradient), the camshaft phasing change is evaluated. If the change after the diagnostic time is smaller than a threshold, a slow response is detected, and if the value is greater, then there is no concern. By detecting a concern, an antibounce counter is incremented otherwise the counter is decremented. This DTC sets when the counter exceeds an adjustable limit.

Possible Causes: • Variable camshaft timing (VCT) unit to camshaft alignment

• Erratic camshaft position due to low oil pressure

• Oil flow restriction in the oil passages or the VCT valve body

• Camshaft advance mechanism binding (VCT unit)

• Damaged VCT phaser

• Radio frequency interference

Diagnostic Aids: This DTC may be accompanied by other DTCs. Diagnose all camshaft position (CMP) sensor DTCs first. If no

CMP sensor related DTCs are present, continue to follow diagnosis for this DTC. This DTC is a functional check of the VCT unit. Diagnose any base engine concerns related to the engine oil pressure or engine timing. Refer to the Workshop Manual Section 303-00, Engine System, Oil Pressure Test, to check the engine oil pressure. Refer to the Workshop Manual Section 303-01, Engine, to check the engine timing and VCT phasers.

P0010 - Intake Camshaft Position Actuator Circuit/Open (Bank 1)

Description: This DTC sets when a low or high voltage on the VCT11 circuit is detected.

Possible Causes: • VCT11 circuit open

• VCT11 circuit short to voltage

• VCT11 circuit short to ground

• VPWR circuit open

• Damaged variable camshaft timing bank 1 solenoid 1 (VCT11)

P0011 - Intake Camshaft Position Timing - Over-Advanced (Bank 1)

Description: This DTC sets when the variable camshaft timing (VCT) position is over-advanced. This DTC sets when the

camshaft timing exceeds a maximum calibrated value or remains in an advanced position.

Possible Causes: • VCT unit to camshaft alignment

• Camshaft timing incorrectly set

• 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

• Variable camshaft timing bank 1 solenoid 1 (VCT11) valve stuck open

• VCT11 circuit open

• VCT11 circuit short to voltage

• VCT11 circuit short to ground

• VPWR circuit open

• Camshaft advance mechanism binding (VCT unit)

• Damaged VCT11 phaser

• Damaged camshaft position bank 1 sensor 1 (CMP11)

• CMP11 sensor circuits open

• CMP11 sensor circuits short to voltage

• CMP11 sensor circuits short to ground

• Radio frequency interference
