    Here's the TSB relating to your P0410 trouble code:

    2001 Chevy Truck S10/T10 P/U 4WD V6-4.3L VIN W
    Emissions - MIL Lamp ON/DTC P0410 Set

    Bulletin No.: 04-06-04-015
    Date: March 22, 2004
    TECHNICAL
    Subject:
    Check Engine Light On, DTC P0410 Set (Replace AIR Pump, Install New Hose Assembly)
    Models:
    1999-2003 Chevrolet Blazer, S10
    1999-2001 GMC Jimmy
    1999-2003 GMC Sonoma
    1999-2001 Oldsmobile Bravada
    with 2.2L or 4.3L Engine (VINs 4, H, 5, W - RPOs LN2, L43, L35)
    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:
    1. Prep vehicle.
    2. Raise vehicle on hoist.
    3. Remove shield covering AIR pump.
    4. Remove hose and vacuum lines from pump and solenoid.
    5. Remove AIR pump inlet hose. Do not re-use.
    6. Disconnect electrical connectors from pump and solenoid.
    7. Remove pump mounting bolts and pump.
    8. Transfer isolators from the old pump to the new pump.
    9. Install new AIR pump and bolts to vehicle. Tighten the bolts to 17 N.m (12.5 lb ft)
    10. Route new hose assembly up between engine and fender. It should come up near the area between the battery and the coolant bottle.
    11. Connect new inlet hose to pump inlet.
    12. Connect old outlet hose to pump outlet.
    13. Connect electrical connector to pump.
    14. Connect electrical connector for solenoid to connector on the new hose assembly.
    15. Connect the hose with the white nipple to the vacuum source hose.
    16. Connect the remaining hose to the shut off valve.
    17. Install shield covering AIR pump.
    18. Lower vehicle.
    19. Remove coolant reservoir nut nearest the battery.
    20. Route new hose assembly between the battery and the coolant reservoir with the solenoid on top.
    21. Install the solenoid bracket onto the coolant reservoir stud and reinstall the nut back into the vehicle.
    22. 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.
  • So, no one out there has any clue what my problem is apparently. Hard to believe. :confuse: I would like to put a code reader on this truck, but the owner before me screwed it up somehow and it won't fit. I am sure my problem is fixable and I'm sure it's not helping my gas mileage or the truck running this way, but at this point I have no choice. Oh well..... :(

    Hi,

    Two Thoughts ...

    1.) Do you have an exterior Antenna? The Antenna needs a good ground at the bottom of the antenna to the body - As the vehicle is older, it may be loose, rusted, etc. I'd buy a new antenna , install it ensuring the inside/underside of the mounting hole is good an clean.

    2.) Most radios "used to " have a "tuning" adjustment for AM. They used to be in the back - or perhaps if you pull off one of the knobs you will see a "pot" to turn. - check your manual. This adjustment helps with antenna impedenct matching between the radio and the Antenna ....

    Good Luck !!
  • I recently had my oil changed at a local lube shop and they stripped the drain plug bolt. I had to get a new oil pan (which they paid for). Can anyone tell me what the factory torque specifications should be for an oil pan drain plug for a 1995 Chevy S-10 with the V-6 engine.

    I just found this forum...read through first twenty pages or so and noticed that two other owners were experiencing very poor fuel economy. I'm getting 19.2 mpg on
    highway at 60mph with no a/c. I have a 2000 Sonoma 2.2L with auto trans.
    I know it should get far better mileage; I had previously owned a '96 S10 2.2L and got over 27mpg with it!

    I noticed that the other two problems like mine received no replies so, I might be wasting my time! Engine runs strong, no hesitation, etc. and truck has less than 63,000 miles...I bought it just 2 weeks ago and my mechanic is scratching his head.

    What should I be looking for? Dealers just scratch their caps and shake their heads. What's wrong? Doe anyone have a suggestion where to begin looking?
  • I am a she by the way, and thank you for all the help. My other concern is if water or moisture has entered the system through the air pump, has this or could this have caused damage to any other parts of my engine? i.e. O2 sensor, spark plugs , etc. I just want to make sure once I fix this problem, there won't be any residual effects.

    I have a 1991 sonoma and recently the e-break light flashes on and off while my engine is running and the e-break is not on. Is there a way i can fix this?
  • joe3891joe3891 Posts: 759
    Clarification please, you listed the engine as a 2.2, is it in fact a 4.3, V6.
    :)

    have you checked the oil pump?

    I have a 2000 S10, I have been having problems with the seat levers. Both
    lower levers have snapped off, the metal they used for attachment looks
    like pretty cheap pot metal! any suggestions on repairing this or re-fabricating
    would be appreciated. thankyou!

    Have you tried resister plugs and wires?
  • chevlvrchevlvr Posts: 18
    I did not read your entire post at first, but you definately have a plug and
    wire problem, pick up some resister plugs and get a good set of plug wires
    and that should alieviate the problem.

    hi, I have a 2000 s10, have had the same problem, try the throttle position
    sensor, good luck!
  • chevlvrchevlvr Posts: 18
    sounds like it could be a sticky choke, just a thought....good luck
  • chevlvrchevlvr Posts: 18
    hi, I have a 2000 s10 2.2L had the same type of problem, I cant remember
    code # I pulled but ended up replacing throttle position sensor, which seems to
    be a common problem on the 2.2L. the real weird thing is that I had a converter
    problem also( sounds like we are in same boat, or atleast were)...good luck!

  • When I take my 95 S10 out of gear the engine revs high. If I leave it in gear and hold in the clutch I can get the engine to take the RMPs down but once it is out of gear it goes right back up. I have no engine light to appear. Any suggestions?

    I recently replaced both handles on my wife 2000 blazer with ones I bought from Ebay. There are a couple of different types, the ones I got have a longer shaft sleve and use a longer screw. The other has a longer shaft sleve with a set screw on the sleve for earlier vehicles that dont have the screw in the center . these both are great easy fixes." Just type in s-10 seat handles under BUY and they'll come up I got ine from snowbuddie1 I thought they were the bust buy for the price.
  • no, its a 2.2L, and I went out and bought the manual so I could try and locate everything, but the stupid book doesn't have a diagram. I found what I think is the air pump near the cat with two tubes coming from it, and disconnected the tubes temporarily and found no moisture or water. Don't know where to go from here!
  • joe3891joe3891 Posts: 759
    The reason I asked is I have never heard of an air pump on a 2.2L OHV engine. I have a 99 2.2 with no pump and once owned a 2000 2.2 OHV and no pump.
    One way to be sure is under the hood is the emissions decal, all the emissions installed are listed there, take a look, you really got my curiosity up. :)
  • We are thinkin of buying a 1989 Chevy Blazer S-10 4WD automatic. But the transmission is slipping. We own a 1986 Chevy S-10 pickup automatic and thought about using the transmission out of it for the Blazer. But this is the question...is the transmission interchangeable with the 4WD? Everything is interchangeable but we arent sure if the 4WD will cause a problem in swapping the tranny out. Thx, Sweets
  • joe3891joe3891 Posts: 759
    If the transfer case bolts on to the back of the transmission the output shaft has to be changed. You need to completely disassemble the tranny to do it, its about the first part you install on build up. :(
  • Anyone who has this problems as well, the result was a lose vacuum hose. I have replaced the hose and it works well now.
  • come to find out, they have just changed the name of it-it is the smog pump, but apparently GM/California got together and decided they didn't like the name anymore and just wanted to confuse all of us. Anyways, I reset the computer, and no code has come back. I think since it has been so humid, that's what got into the air/smog pump, but the heat dried it up. Having the cat replaced at the dealer under warranty next week so we''ll see.
  • i had an 88 s10 did the same thing check the engine computer mine had a crack in the resin and it would overheat the computer and cut out i changed the computer and i worked fine
  • 1987 GMC S15 Engine Surge.
    When I start my truck, if I drive right away without giving a 2 min. warm up time, at the first stop when I push in the clutch, the engine will surge out of control up and down. Eventually it will start to calm down and when the idle has reached the lowest point, it is good to drive again and wont happen until the next day.
    I can avoid the problem by letting it warm up and idle down to the lowest point before driving. The problem is much worse in the winter with cooler temps.
    Any info on this would be greatly appreciated.
    Regards,
    Vernon
  • I have a 1995 S10 with the 4.3L TBI V6. Immediately after I start my truck then drive the engine surges. The problem will go away after I drive my truck for awhile. This seems more prevalent with the AC on. Sometimes the truck will idle down then die especially with the AC on. The engine does not seem to accelerate correctly even after the initial surging occurs.

    I took my truck to a mechanic and they tested some things with engine scanner. One problem they found was that when you accelerate, the engine timing was retarding instead of advancing. The shop told me I should replace the ignition module in the distributor which I did. This seemed to help a little but the problem still exists. I have replaced all of the standard maintenance parts (plugs, cap, rotor, wires, 02 sensor) and the catalytic converter only has 20K miles on it.

    Does anyone have any suggestions on any other items to replace? Why would the AC cause my truck to make this problem worse? I would appreciate any suggestions. Thanks.

    I've been getting that code on my 2000 chevy s10 2.2 auto, the truck normally starts running ok but after a few minutes I get the SES light on and starts acting up. it shifts really hard, it doesn't downshift if I floor the gas, in fact it doesn't do any downshifting unless I stop completely, any ideas?
