P0410 Causes

  • Malfunctioning air pump/air pump relay
  • Faulty air pump check valves
  • Blocked air injection system
  • Blown air injection fuse

P0410 Symptoms*

  • Check engine light
  • The engine may hesitate upon acceleration
  • Noisy air injection pump

*No noticeable adverse conditions in some cases

How Do I Fix Code P0410?

With a P0410 code, the first step is to get it properly diagnosed to figure out what is causing the malfunction in the oxygen sensor system. Using the live data function of the FIXD sensor and app allows you to read and analyze engine data to properly diagnose a P0410 code.

If the sensors are all reading correctly and you’re not comfortable further diagnosing this issue at home, we recommend finding a RepairPal-certified shop to pinpoint the problem and give an accurate estimate for repairs. 

These shops can not only help you figure out what’s going wrong before you waste time and money on the wrong parts, but they also offer a minimum 12-month, 12,000-mile warranty and stand behind all their estimates with guaranteed fair pricing.

How Much Does It Cost to Fix Code P0410?

If you take your car to a shop for diagnosis, most shops will start with an hour of “diag time” (the time spent in labor diagnosing your specific issue). Depending on the shop’s labor rate, this typically costs somewhere between $75-$150. Many, if not most, shops will apply this diagnosis fee to any required repairs if you have them perform the repairs for you. From there, a shop will be able to give you an accurate estimate for repairs to fix your P0410 code.

DIY Steps to Diagnose Code P0410

If you’d like to try to fix code P0410 at home without throwing money at parts, you’ll want to follow the steps below for proper diagnosis.

DIY difficulty level: Beginner

This repair can be attempted by beginner DIYers.

Tools/parts needed (our top picks from Amazon):

STEP 1: USE FIXD TO ENSURE NO OTHER ENGINE CODES ARE PRESENT.

Scan your vehicle to verify P0136 is the only code present. If other codes are present, they must be addressed first.

STEP 2: CHECK FUSES AND RELAY. 

Check the fuse for the air injection pump. If the fuse is blown, replace the fuse and test drive to see if the concern is resolved. Often times if the fuse is blown, it’s due to a failed air injection pump. If the fuse blows again, try replacing the air injection pump and fuse, but make sure to clean out hoses and replace the one-way check valve.

If the fuse is not blown, check the air injection pump relay for function. If it fails the test, replace the relay and test drive to see if the concern is resolved.

STEP 3: INSPECT AIR INJECTION PUMP.

If the relay passes the test, try replacing the air pump, but make sure to clean out the hoses and replace the one-way check valve.

STEP 4: CONSULT A PROFESSIONAL.

If at this point the vehicle is still setting the same code, you may have a more serious problem with your car’s oxygen sensor system, and you should bring the vehicle to a certified shop to have further diagnostic work performed.  

Common P0410 diagnosis mistakes

Prematurely replacing the air injection pump before checking the fuse or relay.
