Sounds like they want to cover all bases. When the truck is first started you should hear the pump run. If it does you don't need the pump. While the engine is running remove the hose from the check vavle, exhaust should not be coming out of the tube, if it does the check valve is bad. There is also a vacuum hose going to the check valve , make sure it is hooked up. It's not to hard to diagnose this code. Pumps are approx. $150.00 Check valves around $80.00

SOURCE: P0441 EVAP Control System Incorrect Purge Flow

Test the purge valve and the vent valve for leaks. This can only be done with a Tech 2 and or a vacuum pump.

SOURCE: secondary air injection system

This is a pump that sits underneath your front bumper on the passenger side. It is about the size of a baseball and has two hoses going into it. I would suggest you replace it yourself as it would cost you about $360.00 if you were to go through the dealer.

Water intrusion is what will typically kill these electric pumps. There is a Technical service bulletin (#04-06-04-015) Regarding this problem, according to the tsb, you will need a new pump and there is a hose assy. #12590627) that has you reroute the pump from future water intrusion or it is guaranteed to fail again.

Although I have had water in the pump I did not see any indication of the inlet hose as the cause. It was suggested that the one way metal check valves ($15.00) that mount to the rt & lt exhaust manifold are worn and allow water from the exhaust to get sucked back into the pump. I first replaced the pump and within a week of dry weather driving the light came back on. I checked the pump and it was again full of water. I just replaced the valves which had deteriorated on the inside. So hopefully this will eliminate the problem. Note - The valves are impossible to remove without removing the 1/2 tubes (held on with 2 nuts) they are attached to the manifold with. The valve threads seize to the tube thread and had to be clamped in a vise to remove - I actually had to hacksaw the valve section to get it off the pipe. Careful as not to damage the threads.

Good luck and try autopartsdirect2you for a new pump and it has life time warranty.

TSB #04-06-04-015 - (Mar 22, 2004)

Condition
Some owners may comment on the check engine light being illuminated. Upon investigation, the technician may find a DTC P0410 indicating that there is a concern in the secondary air injection system.

Cause
Water may have collected in the AIR pump or the vent solenoid and frozen or corroded the pump.

Correction
Replace the AIR pump and install a new inlet hose and solenoid tube assembly using the following procedure:

Prep vehicle.
Raise vehicle on hoist.
Remove shield covering AIR pump.
Remove hose and vacuum lines from pump and solenoid.
Remove AIR pump inlet hose. Do not re-use.
Disconnect electrical connectors from pump and solenoid.
Remove pump mounting bolts and pump.
Transfer isolators from the old pump to the new pump.
Install new AIR pump and bolts to vehicle.

Tighten
Tighten the bolts to 17N·m (12.5 lb ft)

Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle.
Connect new inlet hose to pump inlet.
Connect old outlet hose to pump outlet.
Connect electrical connector to pump.
Connect electrical connector for solenoid to connector on the new hose assembly.
Connect the hose with the white nipple to the vacuum source hose.
Connect the remaining hose to the shut off valve.
Install shield covering AIR pump.
Lower vehicle.
Remove coolant reservoir nut nearest the battery.
Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle.
Use a wire tie to keep the new hose assembly away from the engine. On four cylinder engines, tie to the AIR outlet hose. On six cylinder engines, tie to an available hole in the radiator fan shroud.

I have a service engine soon light on and have hooked up an OBD11 reader to it and got code P0410 pertaining to a secondary air injection problem. hoses are fine, pump is new.


P0410 Oldsmobile - 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

Tech notes: Visually inspect AIR pump and AIR bypass valve harness and connector, if connector are OK, then replaced AIR bypass valve.

When is the code detected? The secondary air injection system does not detect the presence of air in the exhaust when introduced by the secondary air injection system.

Possible symptoms: - Engine Light ON (or Service Engine Soon Warning Light)
- Engine hesitation

P0410 Oldsmobile Description An air pump is used on the vehicle to lower tail pipe emissions on start-up. The Powertrain Control Module (PCM) grounds the Air pump relay control circuit which energizes the Air pump. The PCM also grounds the Air combination valve vacuum control solenoid circuit, which energizes the Air vacuum control solenoid. Vacuum is then applied to both Air combination valve diaphragms which opens the shut off valves. The PCM enables both circuits simultaneously when Air system operations id desired. When the AIR system is active, then Air pump forces fresh air into the exhaust stream in order to accelerate catalyst operation. The AIR combination valves replace the conventional check valves. When the AIR system is inactive the shut off valves prevent air flow in either direction.

Am looking for what the carmd code p0410 means for a 2004 buick ranier - my car md is not working right.


CEL light/code P0410, secondary air system fault.
DTC P0410 - Secondary Air Injection System

Suspect -
Relay/fuse (box B) loc 3 ,15amps
Pump $434(new) / $243 (Remanufactured) / $95 (used,Ebay)
solenoid $73
check valve $18

A new pump, or simulator!

What signals the ECU, if the seconary Air Injection system isn't working?
H20 sensors, if running rich > Xtime throw code!
The pump only runs when the engine is cold, so the air & rich fuel mix is burnt in the exhaust manifold, so there's less Emission.

Service Engine Soon light came on. Took the car to Auto Zone the code P0410 popped up. What does this mean?


This is a secondary air system malfunction code.....

The Secondary Air System pumps outside fresh air into the Exhaust System during cold engine start up. This additional air helps burn up the highly rich exhaust emissions that are produced when the engine is warming up. The Secondary Air System typically has an Air Pump and some tubes or plumbing to route the air. The system also has a solenoid and Check Valve(s) to control the air flow.

Common Problems That Trigger the P0410 Code
  • Defective Check Valve(s)
  • Faulty Air Pump or Air Pump Relay
  • Faulty air control solenoids or vacuum lines
  • System may be restricted or plugged

Check engine light on, diagnostic code 0128 and 0410 keep coming up


P0128 - Coolant Thermostat (Coolant Temperature Below Thermostat Regulating Temperature)

P0410 - Secondary Air Injection System Malfunction
(has to do with exhaust system)

Note: There is a technical service bulletin (TSB) regarding code P0410 for a number of GM models. The TSB calls for the replacement of the AIR pump and the installation of a new secondary injection hose.

I went to autozone because my check engine light was on the put the device on to check the problem and they came up with these troubleshooting codes P0440, and P0410


P0440 - Check Gas Cap to be sure it is tight and not leaking air. Possibly just replace it.

P0410 - Secondary Air Injection system. Typically the check valve near the firewall goes bad. There is also one on the driver's side near the radiator. Could also be a fuse for the fan or the fan itself. The fan/blower is tucked under the left front fender - remove the wheel well liner to get to it. This is an emissions code only and will not effect the operation of the car. The check valves are roughly $200.00/ea. A lot of people choose not to fix this code.
