Code P1485 KIA Description

The P1485 code for KIA vehicles indicates a problem with the EGR (Exhaust Gas Recirculation) Solenoid Vacuum Valve being open or experiencing a short circuit. The EGR system is responsible for recirculating a portion of the exhaust gases back into the intake manifold to reduce nitrogen oxide emissions. The solenoid vacuum valve controls the flow of vacuum to the EGR valve to regulate this process. When the solenoid valve is stuck open or shorted, it can lead to improper EGR operation, affecting engine performance and emissions output. This issue can trigger the check engine light and cause the vehicle to fail emissions tests.
