Tech Notes

There is a factory service bulletin for the following KIA models:

Kia Rio (JB)
Kia Soul (AM)
Kia Optima (MG)
Kia Rondo (UN)
Kia Forte (TD)
Kia Spectra (LD)
Kia Sportage (KM)
Kia Optima (MG)
Kia Sedona (VQ)
Kia Amanti (GH)
Kia Borrego (HM)
Kia Sedona (VQ)
Kia Sorento (BL)
Kia Borrego (HM)

The bulletin provides information on how to inspect and diagnose problems related to the Oil Control Valve (OCV) used in Constant Variable Valve Timing (CVVT), if at any time the OCV is suspected as the caused of rough idling, poor acceleration, camshaft timing misalignment-related trouble codes, misfire-related trouble codes.

P0011 KIA Meaning

The CVVT (Continuously Variable Valve Timing) system is installed to the chain sprocket of the exhaust camshaft. There is no variation in valve timing of the exhaust cam because the exhaust camshaft is driven by the timing belt. The timing of the intake cam is varied by the relative operation the CVVT vane to the housing. The CVVT controller regulates the intake camshaft angle using oil pressure through the OCV (Oil Control Valve). As result, the relative position between the camshaft and the crankshaft becomes optimal, and the engine torque improves, fuel economy improves, exhaust emissions decrease by changing the valve open/close timing of the intake camshaft.

The deviation of the camshaft position from the target point is evaluated during stable driving condition. The Engine Control Module (ECM) accumulates this deviation for a certain period and sets DTC P0011 when the accumulated deviation is too high. The target camshaft position is predetermined value depending on engine speed and throttle angle in the ECM.
