DTC Description
DTC DETECTION LOGIC
| DTC No. | CONSULT screen terms (Trouble diagnosis content) |
DTC detecting condition | |
|---|---|---|---|
| P0022 | A camshaft position B2 ["A" camshaft position - timing over-retarded or system performance bank 2] |
During the retarded control of intake valve timing control, the angle difference between actual angle and target angle is 13 degrees or more. | |
POSSIBLE CAUSE
- Electric intake valve timing (IVT) control actuator (bank 2)
- Harness and connectors [Electric IVT control actuator (bank 2) motor control circuit is open or shorted.]
- Foreign matter caught at the electric IVT control actuator (bank 2)
FAIL-SAFE
| Fail safe mode | Vehicle behavior |
|---|---|
| Device fix mode |
|
| Others | ECM stops the electric valve timing control. (The camshaft returns to the position of most retard angle. When VTC mechanism sticks, camshaft position does not change from position of stuck angle.) |
