The s10 2001 2.2 automatic with approx 50,000 miles has the P0410 code , clear it and in 2 to 3 hundred miles it returns--and my mpg has dropped from about 27 to 22
It may have caused poor mileage. Here is what is going on. http://www.obd-codes.com/p0410 Really a common issue on these trucks.
SOURCE: code P0410 what is the
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 ( P0410 - Secondary Air Injection System Malfunction )
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
Causes: 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 Solutions:
Note: There is a technical service bulletin (TSB) regarding this code 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. The TSB can be found on this ACDelco site.
Additionally, if you simply replace the AIR pump the problem may return again (and again). If you replace the pump, also clean out the hoses and replace the one-way check valve. If this is on a GM model that the TSB applies to, follow those instructions in the link above. In a few cases, people have put a small hole in the rubber cover on the pump which allows any water to drain out.
Also, please 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!
* 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)
Hope this helps (remember comment and to rate this answer).

If the air pump is working then it's going to be the one way check valve at the manifold. It's common for the check valves to go bad before the air pump, check the pipe from the pipe to the manifold too.
Before you get that far i believe there was a TSB and the warranty is 5 years to the emission system on vehicles. Looks like your close to the end of your 5 year so step on it to the dealer while you can still get a deal on this repair.
Good luck and hope this helps.

And some instructions
Removal Procedure
Caution: Allow the engine to cool before servicing the secondary air injection AIR system in order to reduce the chance of severe burns.
1. Remove the clamp from the check valve.
2. Disconnect the AIR hose from the check valve.
3. Remove the check valve from the left side AIR pipe.
4. Remove the left AIR pipe from the exhaust manifold.
5. Before replacing a check valve, test the valve for proper operation.
5.1. Install a vacuum pump to the nipple side of the check valve, AIR pump side.
5.2. Pump the vacuum pump to 10 inches Hg and observe the gauge.
5.3. Replace the check valve if the vacuum bleeds down to zero within 5 seconds.
Installation Procedure
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
1.Install the check valve onto the AIR pipe.
Tighten the check valve to the AIR pipe to 23 N·m (17 lb ft).
2.Connect the AIR pipe to the exhaust manifold.
Tighten the AIR pipe to the exhaust manifold to 20 N·m (15 lb ft).
3. Install the AIR hose to the check valve.
4. Install the check valve clamp.

I am very familiar with this code, there is a GM service bulletin about this problem, in short it says to replace the secondary air injection electric pump assmebly
SOURCE: engine code p0133, p0134, p1133,
All those codes and such an easy fix. ALL of these codes point to your upstream 02 sensor. It's the one on the passenger side of the engine coming off the exhaust, very very easy to get to. Soak that puppy with PB Blaster then remove the electrical connector and remove and replace sensor. TRY to stay away from Bosch 02 sensors, have been known and reported problems with these. In my case, I didn't have a choice but to buy the Bosch, but I haven't had any problems with mine.
Hope this helps, look to get a tad more miles per gallon too.
Testimonial: "Good answer and really appreciate the help. Also was told a PCM recalibration may be needed. Thanks"
