P0022 KIA Possible Causes
- Dirty Oil
- Low engine oil level
- Faulty Valve Timing Control (VTC)
- Valve Timing Control (VTC) harness is open or shorted circuit.
- Valve Timing Control (VTC) circuit poor electrical connector
- Incorrect timing
- Engine mechanical problems
- Damaged Engine Control Module (ECM)
First diagnose P0022 KIA code
Check the "Possible Causes" listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded terminals.
P0022 KIA Tech NotesThere is a factory service bulletin for the following KIA models:
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.

Cost of diagnosing the P0022 KIA code
Labor: 1.0The cost of diagnosing the P0022 KIA code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
P0022 KIA Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of power
- Engine rough idle
P0022 Kia DescriptionThe 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.
