The P0410 code on your 2022 Kia Sportage indicates a general malfunction in the secondary air injection (SAI) system. This emissions control system helps reduce cold-start emissions by injecting fresh air into the exhaust stream.
Understanding Secondary Air Injection
The SAI system pumps air into the exhaust manifold during cold starts. This additional oxygen helps the catalytic converter reach operating temperature faster and reduces hydrocarbon emissions during warmup. The system typically includes an air pump, control valves, check valves, and associated plumbing.
Sportage Engine and SAI
The 2022 Sportage uses turbocharged four-cylinder engines. Not all markets or configurations include SAI systems—verify your vehicle actually has this system before extensive diagnosis. Modern turbocharged engines may use different cold-start emission strategies.
If SAI System Is Present
Common P0410 causes include a failed air pump motor, stuck or leaking air control valves, clogged air passages, failed pump relay, or broken air hoses. The pump motor bearings wear over time, and valves can stick from carbon or corrosion.
Diagnostic Process
Verify the SAI system exists on your specific model. Use Kia GDS to command the system on and listen for pump operation. Check air pump motor function directly. Inspect hoses and connections for leaks or damage. Test the control valve operation. Verify the relay functions properly.
