The P0410 code refers to the emissions system. The AIR pump puts air to the exhaust to lower emissions. It takes in outside air and pumps it through two one-way check valves into each bank of the exhaust.
.
About 90% of the time that this code is set, the one-way check valves have worn out or failed and allow water (which occurs naturally in the exhaust) back into the pump. In any cold climate, especially in climates with higher humidity, this water may be more excessive. The water partially fills the AIR pump, it can then freeze. When the PCM commands the pump on, if the pump is frozen it cannot turn, thus overloading the circuit and "popping" the fuse.

A code P0410 may mean that one or more of the following has happened:

  • Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump
  • Blown AIR pump fuse due to freezing up
Possible solution:
This may be covered under the emissions warranty on the vehicle. If your vehicle is out of bumper-to-bumper warranty, check if the emissions warranty is still valid!
  • Replace the AIR pump AND one-way check valve
  • Test and clean the AIR pump AND test and replace the one-way air check valve
  • Replace the AIR pump inlet hose
  • Replace the AIR pump fuse (found under the hood)

Code po410


P0410 - Secondary Air Injection System Malfunction
Possible causes- Faulty Vacuum hoses damaged
- Faulty Air Pump inoperative
- Air bypass solenoid harness is open or shorted
- Air bypass solenoid circuit poor electrical connection
- Air bypass solenoid leaking/blocked or stuck open/closed
- Air diverter valve leaking/blocked or stuck open/closed

This is likely a pump problem caused by water being sucked into the secondary air injection pump under the hood.

On a 2001 chevy s1o blazer,4.3 engine, what is the secondary air injection system, what does it do, and where is it located


it injects air into the exhaust to reduce emissions, burn off carbon monoxide and hydrocarbons. it is a system of tubes and pump, best bet is diagrams, which i cant post here, so suggest chilton or hayes repair manual $30 at auto stores with trouble shooting, diagrams, and directions.

Engine light came on, code po410 came up.


This has to do with the secondary air pump system, this system is used at cold start-up and involves three components; air pump, solenoid valve and a relay. Many times the valve becomes stuck or clogged, the relay has also been known to fail.

Which sensor do I need to correct code po410


PO410. Secondary air pump code.

Check fuse for air pump. Blown.
Replaced the air pump if it's in Bad shape.
The air pump is only $100 (NAPA) Gotta be water in the air pump. Water gets in air pump...then rapid below freezing conditions the air pump freezes...blows fuse.....set air pump code.

There is a GM bulletin about a new intake tube for the air pump for exactly this problem. This new intake tube should save the air pump, get the new intake pipe/valve the same time you repair or replace the air pump if it's gone bad. Check the fuse first though, good luck.

I have an engine management light come on - tested - came up with a code PO410 - what is the next step?


P0410 is the error code for Secondary Air Injection System Malfunction
The secondary air injection pump pumps air into the exhaust to help heat the catalytic converter at cold start. This lowers the emissions at an otherwise high emission time.
A malfunction means that computer has registered either a pump failure (common on some models), fuse blown, or improper catalytic converter function.
Check your fuses. Whether you find a bad fuse or not have the codes reset. Some auto Zones can read and reset the codes. If the error comes back you may want to consider having the exhaust system checked.Problems with the catalytic converter\converters can have a large impact on your MPG.

I have a 2004 buick rainier and i,m getting a code po410


P0410 Secondary Air Injection System Malfunction
I am very familiar with this failure code, you are going to have to replace the secondary air injection pump, it has a failed motor in it, the code really indicates no airflow from the pump when commanded to be on.
