Secondary Air Injection Pump for Toyota Trucks ⚙️

This emissions pump feeds fresh air into the exhaust during cold starts. By adding oxygen, it helps the catalytic converters light off fast, burning unspent fuel and cutting tailpipe pollution . It’s an OEM-grade fit for Toyota V8 platforms and built to handle moisture, backpressure, and daily heat cycles.

Why this part is needed

Cold engines run rich. Without added air, hydrocarbons and CO spike. This pump reduces cold-start smoke, protects the cats, and keeps the ECU happy so your truck passes inspection.

How it works

An electric motor draws air through an inlet, then pushes it via hoses to the exhaust ports or combi valves. The ECU commands it for a short window after start-up. Check valves stop hot exhaust from flowing back and damaging the unit.

What happens if it fails ⚠️

Common results: check engine light (P0410–P2445 range),rougher cold idle, sulfur smell, higher fuel use, and on some models, reduced power mode. Water ingress can seize bearings or blow the fuse/relay. Long term, catalysts may age faster and emissions tests can fail.
