Genuine 17610-0S030 Secondary Air Injection Pump Assembly

The Genuine 17610-0S030 is a factory OEM secondary air injection pump assembly designed to reduce harmful emissions during cold start conditions. This emissions control component injects fresh air into the exhaust stream to allow for fuller secondary combustion of exhaust gases, helping your vehicle meet strict environmental standards.

Key Features:

• Reduces harmful hydrocarbon (HC) and carbon monoxide (CO) emissions during the cold start phase
• Helps bring the catalytic converter up to operating temperature quickly through heat generated in the secondary reaction
• Electric motor-driven vane pump design delivers air under light pressure
• Can be installed in left or right positions
• Genuine OEM part manufactured to Toyota factory specifications for perfect fit and reliability
• Backed by a 12-month, 12,000-mile manufacturer warranty

How It Works:

The secondary air injection pump operates for approximately 30 to 90 seconds after a cold start, injecting oxygen-rich ambient air into the exhaust manifold downstream of the exhaust valves. This results in post-oxidation of pollutants to form carbon dioxide and water, while the heat generated warms the catalytic converter and speeds up the onset of lambda control.

Important Service Information:

A faulty pump is generally the most frequent cause of secondary air system failure. When the secondary air injection pump has a problem, the engine control unit will automatically detect it and activate the Check Engine warning light. Common fault codes include P0410, P0412, P0415, and P0418.

This genuine Toyota/Lexus part ensures proper emissions control system operation and helps your vehicle pass emissions testing requirements.
