Symptom: Malfunction Indicator Lamp

  P000A 00


Intake Cam Angle Bank 1, Control Failure

Fault symptom

Malfunction Indicator Lamp

On-board diagnosis

Type of diagnosis:

Continuous

Enable criteria:

Rotational speed at least 1000 rpm.
No fault on the camshaft position sensor or solenoid and no chain fault.
The engine must work so that the cam phasing mechanism is comanded to carry out cam phasing. 4 cam phasing cycles must have been executed in each direction and each position shall have been at least 5 seconds.
Engine running.

Fault criteria:

The cam angle changes to the requested position too slowly.
The cam angle cannot assume the requested position.

Fault handling:

Type III
(See section Fault handling III, "Other emission-related components and functions" for more information.)

Checking the wiring harness

Move the wiring harness at several spots and in several directions to reveal intermittent breaks and short-circuits. Check switches, connectors and crimp connections for oxidation, retracted pins and pin clamping force.

Diagnostic help

Diagnosis regards:

Correct oil pressure is required for the cam phasing mechanism to operate. The wrong viscosity or the presence of air due to a low level can generate a diagnostic trouble code. The diagnostic tool contains a special function for checking camshaft control.
Electrical fault in connecting leads or component.

Functions in the diagnostic tool related to the fault:

Test value:
Intake Cam Angle Bank 1
Requested intake cam angle, bank 1
Deviation from Requested Intake Cam Angle Bank 1
Intake Cam Angle Solenoid Bank 1
