What is the P0413 fault code What is the description of Secondary Air Injection System Valve Switch a Circuit Open malfunction? How do you fix the P0413 fault code What are the causes and symptoms of the P0413 error code?
What is the P0413 Fault code? What does it signify?
A P0413 code indicates that the secondary air injection pump valve switch circuit “A” is malfunctioning. The “A”. Circuit doesn’t make sense when there is only one valve switch within the system. However, if you have multiple valve switches, it is worth consulting the vehicle repair manual to determine which circuit is the “A”. The word “Open” In the description, the code indicates a damaged or disconnected cable.
Secondary air injection (SAI), or air blown into the exhaust ports of an engine’s cold engine, has the purpose of reducing harmful exhaust emissions. Older vehicles have a belt-driven pump that draws in ambient air and compresses it to inject compressed air into the exhaust manifold. The powertrain controller module (PCM), uses various valves to control the pump, regulate and distribute pressure. The PCM monitors voltage signals coming from pressure sensors strategically placed to detect fluctuations in SAI system tension. After determining the parameters, the PCM opens all valves to allow fresh air to enter the exhaust system.
The electric air injection pump is available on newer models. These systems have a PCM that monitors the pressure sensors to activate the pump when necessary. The relay control circuit supplies electricity to both the solenoid and air injection pumps in an electrical system. The PCM manages the circuit. The PCM continuously monitors the relay control circuit which activates the pump to make sure that it is operating properly. The air pump relay should be commanded “On” The voltage of the control circuit is close to zero. In the “Off”. The relay’s voltage must be equal to the battery voltage when the command is issued. A P0413 fault code will be set if the PCM detects voltage signals that are too low or not available in this circuit.
The P0413 fault code can affect vehicles of all makes and models, including but not limited to: Volkswagen, Audi Mercedes-Benz, Jaguars, Mitsubishi, Land Rovers, Porsche, Seats, Peugeots, Jeeps, BMW, Toyotas, Lexus, Ford, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Mercedes-Benz, Jaguars, Mitsubishi, Land Rovers, Land Rovers, Porsche, Seats, Peugeots, Land Rover, Lexus, Lexus, Lexus, Lexus, Lexus, Lexus, Lexus, Lexus, Lexus, Lexus, Lexuses that are susceptible to the P0413
Notice Some vehicles do not have a secondary injection system.
Other fault codes that relate to secondary air injection system include P0410 and P0411; P0415; P0416; P0417; P0416. P0417. P0418. P0419. P0419. P041F. P044F. P0491. P0492.
What is the P0413 Fault Code?
The following are the most frequent causes of the P0413 fault code:
- – Damaged wires (melted, snapped), shorted wires or loose, corrosion-prone connectors to control the air injection valve control circuit. High circuit voltage means broken wires. Low indicates a shortcircuit problem.
- – Problems with the connectors or the battery supply cables to reach the solenoid.
- – Switch to the defective air injection system valve
- – Control relay defective for air injection pumps
- Defective air injection pumps
What are the symptoms of the P0413 Fault Code?
You may experience the following symptoms if your vehicle has the code P0413:
- – Illumination at the check engine lights
- – Air injection system pump may not activate
- – An increase of exhaust emissions
- – Rich engine running
- – It smells like exhaust
- – Hessing or squeaking sounds coming from SAI pipes, pump
How do I fix the P0413 fault code?
There are several repairs that can resolve the P0413 fault code.
- Repairing the power relay of an air injection pump that is not working
- – Replacing a defective air injection valve switch
- – Replacing a defective air injection solenoid
- – Replace or repair damaged wiring and connections to relay circuits or valve switches
- – Repair or replacement for damaged wires, from solenoid to battery
- Repairing an air injection pump that is not working properly
How serious is the P0413 fault code?
The SAI system’s purpose is to reduce exhaust emissions, but it is not essential for the operation of an engine. Therefore, it should not be considered serious. The check engine light will usually come on and the driver doesn’t notice anything else. The emission control system is directly linked to P0413. This code will cause the vehicle’s exhaust emission tests to fail.
