Error Code P2445: What It Means & What To Do?

<<See All OBD Codes

The trouble code P2445 can be explicated as Secondary Air Injection System Pump Stuck Off Bank 1. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code.

It is the engine control module which would examine the secondary air injection system pump. This trouble code would be set by the ECM when the secondary air injection system pump would not be as per the parameters set by the manufacturer.

What causes this problem with the Secondary Air Injection System Pump Stuck Off Bank 1?

• Issue of unbolted air pump harness
• Unacceptable electrical connection in the air pump circuit
• Pressure sensor might be flawed
• Unusable air switching valve
• Faulty air pump fuse
• Malfunctioning vacuum hose
• There can be inoperative air pump assembly
• Some issues related to the pressure sensor harness

1. Exhaust System Parts - Your exhaust system begins at the engine with the purpose of removing toxic gases and fumes from your vehicle. The components are a series of pipes, catalytic converters, sensors, mufflers, and often a resonator, as well as other emission devices. Thus, replace damaged exhaust system now!
2. Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
3. Electronic Control Unit – The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
4. Air Injection Pump – Check for faults in the air ignition pump and repair/replace as required. Buy new air ignition pump now!
5. Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
6. Diagnostic Tool – Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2445 here:

Common Symptoms

• Illumination in the service engine soon light
• There might be a lot of weird noises coming from the failed air pump
• The car engine might stumble or hesitation upon acceleration

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 P2445:

• You must fix the defective secondary air injection pump
• Make sure to mend the faulty wiring or connectors that are associated with the air pump
• It is essential to restore the flawed fuse
• Repair or replace the quirky serpentine belt

We have stocked a wide range of best priced 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 and a lot more to help you out in fixing your car.

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

• 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 P2445 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 P2445 Code

The most common mistake which is made by a lot of mechanics is that they remove and bypass the secondary air injection pump. The automobile might not intended to run without this air pump and could potentially run badly if it has been removed or bypassed. Many people remove the air pump and purchase a smaller serpentine belt to bypass it. This may not turn out to be a good idea and this issue should be repaired properly by a qualified technician.
