P0410 on Toyota
Secondary Air Injection System Malfunction
P0410 on Toyota vehicles indicates secondary air injection system malfunction. Au7o has documented this code across 2 Toyota models — most commonly on Sequoia, Tundra. P0410 indicates the engine computer detected a malfunction in the secondary air injection system, which pumps fresh air into the exhaust during cold starts to help the catalytic converter heat up and burn off pollutants faster. The system uses an air pump, valves, and hoses, and the computer monitors whether the expected airflow and resulting oxygen-sensor response actually occur. When the system doesn't perform as commanded — too little or no airflow detected — it sets this code. It generally points to a failed pump or stuck valve and primarily affects emissions, especially during the first minutes after a cold start. Typical repair costs on Toyota range from $100 to $4,000, depending on the specific model and root cause.
Common Causes of P0410
- •Failed secondary air injection pump (seized or worn motor)
- •Stuck or faulty air injection / check valve
- •Vacuum or electrical control problem to the air switching valve
- •Cracked, disconnected, or clogged air injection hoses
- •Moisture or corrosion damage inside the air pump
- •Blown fuse or relay for the air pump
- •Faulty wiring or connector in the air injection circuit
P0410 on Toyota by Model
Toyota Sequoia(2 issues)
- Secondary Air Injection System Failure (2UZ-FE)2001-2009
The 4.7L 2UZ-FE's secondary air injection system fails due to corroded air switching valves (ASVs) and seized air pumps. Moisture enters the system and corrodes internal components. Causes check engine light with P2440/P2442 codes.
- Secondary Air Injection Pump Failure (3UR-FE/i-FORCE)2008-2019
2nd-gen Sequoias with the 5.7L 3UR-FE also suffer from secondary air injection pump failures, similar to the 1st gen but with updated part numbers. The pump seizes from internal moisture corrosion, triggering P2440-P2445 codes and check engine light.
Toyota Tundra(1 issue)
- Secondary Air Injection Pump Failure2005-2013
The secondary air injection pump is prone to failure due to water intrusion. The electric motor is located in the wheel well with moisture exposure, and the rubber boot covering the motor traps water, causing the pump to short circuit. This triggers check engine lights with codes P2440, P2443, P2445, P2447, P0418, or P0419. Some vehicles may enter limp mode.

What does P0410 mean on Toyota?▼
P0410 stands for "Secondary Air Injection System Malfunction." P0410 indicates the engine computer detected a malfunction in the secondary air injection system, which pumps fresh air into the exhaust during cold starts to help the catalytic converter heat up and burn off pollutants faster. The system uses an air pump, valves, and hoses, and the computer monitors whether the expected airflow and resulting oxygen-sensor response actually occur. When the system doesn't perform as commanded — too little or no airflow detected — it sets this code. It generally points to a failed pump or stuck valve and primarily affects emissions, especially during the first minutes after a cold start. On Toyota specifically, this code is documented across 2 models.
What causes P0410 on Toyota vehicles?▼
Common causes on Toyota: Failed secondary air injection pump (seized or worn motor), Stuck or faulty air injection / check valve, Vacuum or electrical control problem to the air switching valve, Cracked, disconnected, or clogged air injection hoses, Moisture or corrosion damage inside the air pump.
