Guide To P2447 OBD Error Code Solutions

This problem is most commonly triggered in cold weather conditions. When the one-way check valve which protects the secondary air injection pump goes bad, water in the form of condensation gets into the pump and locks it up. This can cause pump failure, or overload the electrical circuit, blowing the fuse. Another possibility is that engine exhaust that has become too hot and has damaged the wiring and connections involved in the air injection system.

What causes this problem with the Secondary Air Injection System Pump Stuck off Bank 2?

• Malfunctioning air pump assembly
• There can be inoperative pressure sensor
• Imperfect air pump fuse
• Broken vacuum hose
• There can be distorted vacuum switching valve
• Air pump harness might be open or small
• Air pump circuit might have inadequate electrical connection

1. Electronic Control Unit – ECU monitors the temperature differences in the boost converter with the help of the temperature sensors to prevent the converter from overheating and malfunctioning. Thus, replace faulty ECU immediately.
2. Exhaust System Parts - Malfunctioning exhaust system parts may lead to a noisy engine exhaust. A significant decrease in the fuel efficiency, power and acceleration are likely to be observed first as soon as there is a fault in the exhaust system parts. So it is important to change them. Log on to Parts Avatar now for supreme quality auto parts.
3. Air Injection Pump – Faulty pump can cause the water to enter the system and damage the components badly in cold weather. Thus, if it is bad, it needs immediate replacement.
4. Engine Control Module - ECM failures and faults can be very difficult to find and resolve as these are very rare and might require a complete reprogramming of the system to avoid wrong codes from getting stored in the system, leading to misdiagnosis. Replace it now!
5. Powertrain Control Module - Faulty PCM can disrupt the normal functioning of the vehicle by affecting the transmission system and the fuel delivery system. This will cause the system to store wrong OBD error and thus can lead to misdiagnosis.
6. Diagnostic Tool - In order to be that DIY guy, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so, so why not have a look?

We care for our customers and that’s why we can totally understand your problem. That’s the reason why we have listed out some major symptoms behind the flashing up of OBD Code P2447. They are mentioned here as follows:

Common Symptoms

• Check engine light can start flashing up
• The auto exhaust might not burn a lot of fuel without the air pump working and might also clog the exhaust catalyst faster
• The automobile might not clear emissions tests

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2447:

• Rehabilitate the defaults in the wiring or connections to the air injection system
• Carefully adjust the faults in the air pump for the secondary air injection system bank 2
• Recondition the non-functioning secondary air injection system pump relay

Now are you thinking that from where will you purchase these car parts? You have arrived at the right place. We at Parts Avatar care for our customers, that’s why we provide best quality of pcm, exhaust system parts, vacuum hose, pressure sensor, air injection pump, air injection system parts, air pump fuse, air pump assembly, air pump control valve, air injection check valve at marketable prices.

Do you wish to diagnose P2447 error code easily? Here are some steps which you should follow in order to diagnose this fault code:

• Check for any set of DTCs, and capture the freeze frame data, including the order in which the codes occurred.
• Clear all codes and test driving the vehicle to see if they return (if they don’t, this could indicate an intermittent condition, which is trickier to diagnose).
• Visually inspect all system wiring and connectors for damage or shorts.
• Inspect secondary air injection system fittings and hoses for cracks, breaks, or heat damage.
• Test system fuses, replace, and run the secondary air injection system to see if the fuses blow again (indicating possible pump failure).
• Inspect the one-way check valve to see if it’s allowing condensation to enter the pump.

Common Mistakes When Diagnosing The P2447 Code

Most of the mechanics make a mistake of clearing the ECM memory codes before inspecting the freeze frame data for the main failure problem, so because of that the failure might be duplicated and repaired

Another mistake might be failing to clear the ECM codes after the codes are fixed.

Big mistake which is made by a lot of technicians is that they fail to inspect the failure before attempting testing and repairs.
