Tracking Down P0446 on Your 2022 Hyundai Kona
Your 2022 Hyundai Kona has set a P0446 code, pointing to an electrical malfunction in the EVAP vent control circuit. This first-generation Kona (OS platform) with the 2.0L Smartstream MPI engine uses a Canister Close Valve (CCV) to manage evaporative emissions. The PCM has detected that the CCV circuit isn't operating within electrical specifications.
The Kona's compact subcompact crossover design keeps EVAP components in a tight package. P0446 on this platform typically traces to a straightforward electrical cause. With Hyundai's warranty likely still active for a 2022 model, the fix should come at no cost.
Symptoms You May See
- Check engine light on with P0446
- Fuel pump nozzle clicking off early during fill-ups
- EVAP system readiness monitor not completing
- Possible faint fuel odor
- May appear with companion codes like P0441
Suspect Ranking
- Canister Close Valve (CCV) Malfunction (High Likelihood): The CCV solenoid near the charcoal canister is the primary P0446 cause on Hyundai vehicles. The compact Kona places this component close to the rear. Parts $45–$90, labor $80–$170 — likely warranty-covered.
- CCV Connector or Terminal Issue (High Likelihood): Moisture and road exposure can corrode the CCV connector. On the Kona's smaller platform, connector access is easier but exposure to splash-up is significant. Repair costs $50–$130.
- Fuel Tank Pressure Sensor (FTPS) Fault (Medium Likelihood): The FTPS can send incorrect readings that affect vent circuit evaluation. Replacement runs $85–$210.
- Wiring Damage (Medium Likelihood): The CCV wiring route on the compact platform passes through areas where road debris and heat can cause damage. Repair costs $80–$240.
- Purge Control Solenoid Valve (PCSV) Cross-Fault (Low Likelihood): A stuck PCSV can create abnormal EVAP pressure affecting vent circuit readings. Replacement costs $70–$180.
Diagnostic Approach
- Confirm P0446 with an OBD-II scanner and check for companion codes
- Locate the CCV near the charcoal canister at the rear
- Inspect the CCV connector for corrosion or water intrusion
- Test CCV solenoid resistance against Hyundai specs
- Apply 12V to verify CCV operation — listen for a click
- Check wiring from the CCV to the PCM for damage
Cost Breakdown
- CCV replacement: $125–$260
- Connector repair: $50–$130
- FTPS replacement: $85–$210
- Wiring repair: $80–$240
- Diagnostic fee: $75–$130
Can I Drive With P0446?
Yes. P0446 is strictly an emissions circuit code. Your Kona's 147-hp engine, CVT transmission, and optional AWD all work normally. No safety or drivability impact.
Warranty Check
Your 2022 Kona should be within Hyundai's 5-year/60,000-mile basic warranty. The federal emissions warranty covers EVAP components for 8 years/80,000 miles. Visit your dealer before considering out-of-pocket repairs.
