Tip & How-To about Chevrolet S 10

Error Code P0410

Here's the story on the P0410:

The AIR pump adds air to the exhaust stream to lower emissions. It does this by taking in outside air and pumping 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 the northeast 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.

As far as the location of the fuse, it is in the right front fender well beside the battery, and in front of the horn there.

Sometimes replacing the fuse will fix all your problems and you are all set until next winter when it all happens again.

Also, sometimes water is allowed to enter the pump through the intake side of the system (just a 5/8" hose behind the fan shroud) and ruins the system that way. -I'll talk about that in a moment.

GM says that when this system failure occurs due to water intrusion, the pump MUST be replaced. I have had decent luck just blowing the pump out with direct power provided by a test bettery out of the vehicle, and saving the customer some $$$ :thumbsup:

GM has also released a remote air intake kit that includes a longer 5/8" hose, a control solenoid, and a one-way check valve to eliminate most possibility of water intrusion.

Like I said before, sometimes just blowing out the motor and replacing the fuse will solve your problem. BUT, to truly repair the problem correctly the AIR pump, the fuse, and the exhaust check valves must be replaced, and the remote air intake kit must be installed. :banghead: $$$

I have much experience with this AIR system. Here in the northeast it is a BIG problem, and we have replaced at least 100 AIR pumps in the last 2 years or so.

If your vehicle is still under warranty, then you are lucky. --> The exhaust check valves usually wear out after 3-4 years thus, putting most vehicles out of warranty coverage. :sly:

Hope this explains the infamous P0410.

1999 Saturn p0410


P0410 - Secondary Air Injection System Malfunction
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.

Possibly symptoms include:
MIL illumination obviously
Hesitation on acceleration
Noise from a bad/stuck AIR pump

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

Hope this helps and just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa.

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)

Note that 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!

It is really only an emissions issue and won't harm your car's engine ot drivetrain. It will however mean you won't pass emission testing if you live somewhere that tests for that like I do!
