Seven out of every nine-car users should expect to get the P0410 obd2 error code from time to time. The P0410 is a DTC-related error code that prompts vehicle owners of some irregularities in the emissions system. The code calls the attention of the user to the inaccuracies of the air levels detected by the O2 sensors.

Thankfully, there are easy steps to understanding the causes of this problem; more so, getting it fixed. Let’s get started.

Definition of Code P0410

The P0410 obd2 is a common error code associated with the Secondary Air Injection Malfunction of a vehicle. This probably sounds like gibberish at this point since you don’t have a Master’s in Mechanical Engineering. Read on; it gets clearer we promise!

P0410 Meaning

P0410 Meaning

Engineers or vehicle owners detect the P0410 code when the Engine Control Module (ECM) shows symptoms of a malfunctioned Secondary Air Injection System. The ECM only makes this detection when the vehicle’s oxygen sensor isn’t functioning at its best. It becomes hard to detect the oxygen level in the exhaust when the air injection system is working.


  • Slow Engine Response Upon Acceleration: One of the most common symptoms of the obd2 P0410 code is the redundant response to acceleration. The vehicle results in slow acceleration when the air injection system does not function optimally
  • Noisy Air Injection Pump: Since the air injection system can barely handle overflow or insufficient oxygen level, the pump starts to get noisy
  • Fluctuating Check Engine Light: The fastest way to predict when or how to fix the P0410 code is by checking the fluctuation in the check engine light


Prevention we know is better than cure. To better prevent the error code P0410 in the future, you should get acquainted with its causes. In answering your question on how do you fix a secondary air injection system malfunction, let’s go through its causes.

  • A blocked air injection system
  • Faulty air pump or relay system
  • Blown air injection fuse

How Serious is Code P0410?

The impact of the P0410 code error on your vehicle’s overall performance falls between low and medium. Of course, the urgency of the error code can not be weighed with having an overused brake pad since it would not prevent your vehicle from running.

You’d only notice increased emissions from your vehicle if the error is left unattended over a short period. However, if you continue to ignore the warnings, the vehicle would continue to fail emission tests which can be dangerous for driving.

How to Fix and Diagnose P0410 obd2

How to Fix and Diagnose P0410 obd2

From knowing the causes of the obd2 P0410 code, we can now deduce the right method for diagnosing and repairing. 

  • First, run a complete diagnostics for other errors 
  • Look into the air injection pump (around the fuse section). Should you notice a blown fuse, kindly change it then test drive the vehicle for any changes
  • If after a few hours or days the fuse blows out again, try changing the injection pump with a new fuse
  • While making these replacements, ensure you clean the hoses thoroughly and consider changing the 1-way check valve  
  • If the vehicle’s fuse is still in great working condition, however, check the condition of the pump relay function. You’d have to change the air pump relay if the test fails then drive around to check for any changes

Tools You Need

To know how to fix the obd2 code P0410 on your vehicle, you need some essential tools to get the job done.

  • Basic hand tools from your toolbox
  • Multimeter

A Common Mistake you must Avoid When Diagnosing P0410

When diagnosing the problem from the error code, avoid replacing the air injection pump without checking the condition of the fuse or relay.  A lot of people make this common mistake and end up spending double the time and effort to correct the P0410 code error. 

Secondly, always ensure that the hoses are cleaned out properly when trying to fix the secondary air injection malfunction. Blockages of any kind would disrupt the easy flow of oxygen which tampers with the oxygen level readings.

Tips to Further Avoid the P0410 obd2 Error

We get lots of how do I fix code P0410 questions but people fail to ask for the things to do to prevent them in the future. Interestingly, the P0410 symptoms are pretty conclusive to helping you correct them but they sometimes take time to reflect. 

Both the primary and secondary air injection systems work to minimize HC and CO emissions from your vehicle. Here are a few tips on how to further avoid the P0410 error once you’ve learned how to fix the P0410 code;

  • Get Better Fuels: “Premium” fuels contain active cleaning agents that contribute to the vehicle’s fuel combustion which also reduces the job of the air injection systems
  • Change the Air Filter Regularly: Getting the air filter clogged up reduces the amount of air or oxygen level directed to the engine. When the air filter sieves the majority of the contaminated air, the air injection system is left with little to do
  • Reduce Idle Time: Having the car running unnecessarily for long hours would make the air injection system work as twice it normally would when the vehicle is in motion

Estimated Cost of Repairing Obd2 P0410 Code

Attending to the error code P0410 would surely cost you some money even when you decide to explore the DIY alternative. The cost for the parts should range between $800 and $900 without including the cost of hiring an expert to fix your P0410 code error. Here’s a rough estimate of the amount to expect on each item when fixing the error code.

  • Fuse = $12
  • Air Pump = $600-$750
  • Air Pump Relay = $60-$85


Your vehicle’s Engine Control Module (ECM) only detects the error P0410 code when the air injection pump test fails. The ECM automatically senses that some part of the secondary air injection system isn’t functioning at its best. If the test becomes inconclusive, the ECM reboots and demands an active test.

The P0410 code can be fixed using the tools explained earlier without expecting major complications. Ensure you keep the fix as basic and simple as possible without overlooking the obvious. The vehicle would not require advanced solutions as a result of the P0410 obd2 error code.
