P0411 on a 2022 Toyota Camry
Secondary Air Injection Insufficient Flow
P0411 on a 2022 Toyota Camry indicates secondary air injection insufficient flow. It usually stays drivable short-term but should be diagnosed promptly. The most common cause is failed secondary air injection pump motor (typically $300–$1,200). Confirm the root cause before replacing parts.
What does P0411 mean on a 2022 Toyota Camry?
P0411 is set when the engine control module commands the secondary air injection (SAI) system to inject air into the exhaust during cold start and does not detect the expected oxygen reading at the upstream O2 sensors. The SAI system is a separate pump that blows fresh air into the exhaust manifold for the first 60–90 seconds after cold start, helping the catalyst light off faster and reducing cold-start emissions. P0411 means that air injection is not happening — usually because the SAI pump, check valve, or control valve has failed.
This guide covers P0411 across the 2020-2024 Toyota Camry generation — the symptoms, causes, and diagnostic steps below apply to every model year from 2020 through 2024.
Is it safe to drive a 2022 Toyota Camry with P0411?
In most cases a 2022 Toyota Camry stays drivable for short trips with P0411 active, but diagnose and repair it promptly. This is a low-severity code — ignoring it can lead to further damage or a failed emissions test.
What are the symptoms of P0411 on a 2022 Toyota Camry?
- Check Engine Light is illuminated
- Whirring sound from the SAI pump during cold start (or absence of one)
- Slightly elevated cold-start emissions
- Vehicle will fail emissions / smog testing
- No noticeable drivability symptoms once warm

How to diagnose this on a 2022 Toyota Camry
-
Listen for the SAI pump on cold start
On a cold engine (sat overnight), start the vehicle and listen for the SAI pump — a distinct whirring or humming sound from under the hood for 60–90 seconds. Silence at cold start means the pump is not running. Note: SAI does not operate on warm restarts, so the test only works on a truly cold engine.
Tools: Cold engine (sat overnight)
-
Test the SAI pump electrically
Locate the SAI pump (often in the engine bay or under a fender liner). Disconnect the connector and apply 12 V directly. A working pump runs immediately. Silence confirms a dead pump.
Tools: Jumper wires, 12 V supply (battery)
-
Inspect the SAI hose
Trace the air hose from the pump to the exhaust manifold area. Cracks, splits, or disconnections are common — especially on rubber hoses that have spent 10+ years near hot exhaust components. A failed hose means the pump runs but no air reaches the exhaust.
Tools: Flashlight, Inspection mirror
-
Test the combination / check valve
The SAI combination valve prevents exhaust from back-feeding into the pump. Remove and inspect — should freely allow air in one direction and seal in the other. Carbon buildup on the valve from years of exhaust exposure is the typical failure mode.
Tools: Service manual procedure, Carb cleaner
-
Read freeze-frame conditions
Note the engine temperature, vehicle speed, and time-since- start in the freeze frame. P0411 only sets within the cold- start enrichment window. If freeze frame shows the engine already warm, suspect a sensor or wiring issue rather than the pump itself.
Tools: Scan tool with freeze-frame data

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.
NHTSA #11028712 - ENGINE Aug 7, 2025
The specific condition covered by this program is for a small engine coolant leak that can occur from the flow shut-off valve that can allow coolant to drip on other parts of the vehicle. This can cause "Engine Maintenance Required" to be displayed on the instrument cluster or cause the A/C not to function normally. Although the flow shut-off valve is covered by Toyota’s New Vehicle Limited Warranty for 36 months or 36,000 miles (whichever comes first), we at Toyota care about the customers’ ownership experience. Toyota is providing coverage for repairs related to Flow Shut-off Valve Coolant Leak.

About the 2020-2024 Toyota Camry
The 2020-2024 Toyota Camry was commonly sold with the following powertrains: 2.5L I4, 3.5L V6, 2.5L Hybrid I4. Common trims include LE, SE, XLE, XSE.
Why P0411 is rare in the US fleet but common on European cars
US-market vehicles largely phased out secondary air injection in the 2010s as more efficient catalyst designs made it unnecessary. European-market vehicles continued using SAI well into the 2020s for tighter Euro 6 standards. As a result:
- VW, Audi, BMW, Porsche, Mercedes (2003-2018) — chronic SAI pump failures. The pump motor is often the most common failure point on these vehicles.
- US Domestic (Ford, GM, Chrysler 2005-2012) — used SAI on some platforms; eventually deleted.
- Most US vehicles 2015+ — no SAI system, so P0411 doesn’t apply.
If P0411 sets on a US-spec vehicle from the late 2010s or newer, double-check that the vehicle actually has an SAI system before diagnosing.
Carbon clogging in SAI passages
A common longer-term failure mode: SAI passages in the exhaust manifold accumulate carbon over years of use. Eventually airflow is restricted enough that even a working pump cannot deliver enough oxygen to the upstream O2 sensors during cold start. Cleaning the passages requires manifold removal — labor intensive. Some shops decline this repair and quote a full SAI delete (where legally permitted).
Drive cycle to verify a P0411 repair
P0411 only re-sets during cold-start enrichment. After any repair:
- Cold soak the engine 8+ hours
- Cold start and idle 2.5 minutes
- Drive a normal cycle, return home
- Repeat for 2-3 cold starts before assuming the fix held
A single warm-restart test cannot reproduce or rule out P0411.
