code p0410 refers to secondary air injection(AIR) system---malfunction====causes --wiring---AIR valve---AIR solenoid---ECM
check /replace the air solenoid and/or valve.
Diagnostic Test Code (DTC) P0410 indicates that your secondary air injection system is not functioning properly.
Not all 2001 Chevrolet Bazers are equipped with secondary air injection. The secondary air injection system was added to vehicles that were to be sold in certain areas where the emissions laws required it, like the State Of California.
The Powertrain Control Module (PCM) monitors the system by commanding the secondary air blower motor to run and the air injection solenoid to open. This causes additional oxygen to enter the exhaust system. The PCM then monitors the signal from the oxygen sensors to see if the commanded air has in fact, entered the exhaust system. Code P0410 sets when the PCM has commanded the blower motor on and the solenoid open and there is little or no change in the oxygen sensor signal.
GM has had some problems with these systems and there has been a Technical Service Bulletin (TSB) issued that addresses some of the known concers. Below is a brief description of the TSB and the issues involved.
Bulletin No.: 04-06-04-015A
Date: November 28, 2006
TECHNICAL
Subject: LN2, L43 or L35 Engine SES/MIL Light Illuminated, AIR Pump Ingesting Water and DTC P0410 Set (Replace AIR Pump and Inlet Hose Assembly)
Models: 1999-2003 Chevrolet Blazer, S10 1999-2001 GMC Jimmy 1999-2003 GMC Sonoma 1999-2001 Oldsmobile Bravada
with Vortec 2.2L I4 or 4.3L V6 Engine (VINs 4, 5, W - RPOs LN2, L43, L35) Condition
Some customers may comment on the SES/MIL 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...
The bulletin goes on and gives detailed information on how to perform the repair and the part numbers of the replacement parts needed to do so. Your local dealer can provide the parts for you and you can probably get them to print out a complete copy of the bulletin for you. It is not really hard to do if you want to do this yourself.
Leave it to GM to use a computer code to tell you your engine died. The AIR system was a mistake they felt like was best corrected by continuing to use it. The system is similar to EGR function where it injects air into the exhaust for emissions. When it screws up, and it does often, it makes the car run horrible and is usually expensive to fix because the parts are hard to find. I would call a local GM dealer, give them the codes and see what they estimate the cost to fix it is. You might consider trading it in after that.
that code indicates a problem w/ the air injection system, a part of the emissions system. you should check the air pump, solenoid, check valves and vacuum hoses of that system. the emissions sticker under the hood should give you a detailed enough diagram of where the components are
