The P2443 fault code in automobiles refers to a problem with the Secondary Air Injection System Switching Valve Stuck Closed Bank 2. The most common symptom of this issue is the illumination of the Engine Light or Service Engine Soon Warning Light.

The cause of this fault code could be a faulty Vacuum Switching Valve (VSV), open or shorted VSV harness, poor electrical connection in the VSV circuit, faulty Pressure Sensor, or faulty Air Switching Valve.

The importance of repairing this issue lies in the fact that it can lead to increased emissions and decreased fuel efficiency.

The repair difficulty is moderate, and the fix involves visually inspecting the related wiring harness and connectors, checking for damaged components, and looking for broken, bent, pushed out, or corroded connector’s pins. The repair time is estimated to be around 1.0 hour.

  • Another cause of P2443 is a faulty Pressure Sensor.
  • Lastly, a faulty Air Switching Valve can also be the reason behind this fault code.

Below are some possible fixes for the automobile fault code p2443, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code p2443, you need to check the possible causes listed above.
  • Visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code P2443 refers to the Secondary Air Injection System Switching Valve Stuck Closed. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for most shops to charge between $75 and $150 per hour.

Other factors that may influence the cost include the severity of the issue, the type of vehicle, and the location of the repair shop.

The P2443 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 switching valve regulates the movement of the air and is controlled by the Vacuum Switching Valve (VSV). The Engine Control Module (ECM) monitors the system and detects malfunction using a pressure sensor located on the air switching valve. The P2443 code indicates that the switching valve is stuck closed on one bank of the system.

What are the possible causes of the P2443 fault code?

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the P2443 fault code.
