The automobile fault code P2446 is related to the secondary air injection system.

The diagnosis and fixing cost of this fault code is influenced by several factors. The estimated repair time for this fault code is 1.0 hour.

The cost of repair is commonly charged between $75 and $150 per hour by most auto repair shops. The cost may also vary depending on the severity of the issue and the type of vehicle. It is important to get the fault code diagnosed and fixed as soon as possible to avoid further damage and costly repairs.

The P2446 code refers to a malfunction in the secondary air injection system.

The system pumps secondary air to the exhaust manifold to activate the catalyst when warming up the engine. The air is supplied by the air pump and pumped to the exhaust manifold through the air switching valve. The ECM monitors the system and detects malfunction using a pressure sensor located on the air switching valve.

The code indicates that the secondary air injection system pump is stuck on bank.

What are the possible causes of the automobile fault code P2446?

If you see the engine light on or service engine soon warning light, it could be due to the P2446 fault code. This code is usually caused by a faulty air pump fuse, vacuum hose, air pump assembly, or a faulty pressure sensor. It could also be due to an open or shorted air pump harness or poor electrical connection in the air pump circuit or pressure sensor circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

How can I fix the P2446 fault code in my car?

If you’re experiencing the P2446 fault code in your car, which is indicated by the engine light being on, you can fix it by checking the possible causes such as the air pump fuse, vacuum hose, air pump assembly, faulty pressure sensor, air pump harness, and pressure sensor harness. Inspect the related wiring harness and connectors for any damage or corrosion. Look for broken, bent, pushed out, or corroded connector’s pins.

Is it necessary to visually inspect the wiring harness and connectors to fix the P2446 fault code?

To fix the P2446 fault code, it is necessary to visually inspect the related wiring harness and connectors.
