Guide To P0413 OBD Error Code Solutions

<<See All OBD Codes

Is your car engine stalling? Is there a reduced performance and lack of acceleration? Did you notice Check Engine light illuminated on the dashboard? This may lead to OBD code P0413 getting stored in the Powertrain Control Module thus indicating the problem of Air ignition system.

OBD Code P0413 means Secondary Air Injection System Switching Valve A Circuit Open

OBD code P0413 means that the powertrain control module (PCM) has detected a malfunction in a secondary air injection (SAI) system switching valve circuit. This particular switching valve has been given the designation A. The A refers to a particular switching valve in a system that uses multiple switching valves, or the only valve if there is just one switching valve.

One-way valves, switching valves, anti-backfire valves, and bypass valves, controlled by the PCM, are utilized to regulate and distribute air pressure as well as to protect the SAI pump. The PCM receives voltage input signals from strategically placed pressure sensors to monitor fluctuations in SAI system pressure. When the required parameters are reached, the PCM electronically opens the necessary valves and allows secondary air to be pumped into the exhaust system. Some vehicles are equipped with SAI systems designed with an electronic pump. In this type of system, the PCM monitors pressure sensors and activates the pump when required. If the PCM detects a voltage input signal from the SAI switching valve (designated as A) that is too low or non-existent, a code P0413 will be stored and a malfunction indicator lamp may be illuminated.

What causes this problem with the Secondary Air Injection System Switching Valve A Circuit Open?

• Faulty/failed air injection pump.
• Faulty/failed wiring to and from the pump.
• Faulty/failed air bypass solenoid harness.

1. Air Injection Pump - Check for faults in the air ignition pump and repair/replace as required. Buy new air ignition pump now!
2. Air Bypass Solenoid Harness - Sometimes the solenoid harness can also be faulty and should be replaced immediately.
3. Engine Control Module - Faulty ECM can cause wrong error to store in the system and sometimes not noticing the error at all, thus hampering the performance. Buy new control modules from us now!
4. Air Injection System - Any problem with the air injection system has to be corrected and thus may require immediate replacements. Buy air intake components from us.
5. Diagnostic Tools - Use factory grade diagnostic tools to resolve OBD code P0413 error. Buy quality parts now!

• Engine stalling and rough idles

Have a look at some ways with which you can correct the P0413 code:

• Damaged wiring to the air injection system replacement
• Faulty air injection pump replacement
• Inspecting and repairing one-way check valves.

We are sure that now all your issues would be resolved.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P0413 code to be stored:

• Scans codes and freeze frame data in order to verify the problem and check if the code is really present.
• Clear the code and retest the vehicle under similar conditions to see if the error reappears.
• Visually inspect all the associated wiring for the air injection system and repair as necessary.
• After clearing the code, a test drive will reveal if the P0413 returns immediately.
• If it doesn’t, the issue could be intermittent or temperature dependent. If it does return, a fuse may be blown and your mechanic will check that next.
• If the fuse is fine, chances are high the pump itself is defective and will need to be replaced.
• Check PCM for faults and replace or reprogram as required.

Common Mistakes When Diagnosing the P0413 Code

Sometime the individual fails to inspect and repair the one-way check valves inserted in the hoses leading to the exhaust pipe. If the pump is replaced with a still defective valve, chances are high the pump will fail shortly after.
