CEL is Throwing Code P0410 - Could Use Help
For the record this is the red car.
Here is what I have found so far:[I]

Code P0410 is associated with the Pulsed Secondary Air System. This system functions when the car is cold by injecting air into the exhaust ports. The amount of air is regulated by an air control valve which is controlled by the ECM. When fresh air reacts with unburned exhaust gasses, the exhaust gas temperature rises. This rise in temperature promotes faster warm up of the catalytic converter, resulting in cleaner emissions during cold start up. The pump activates for a short period (i.e. less then 60 seconds).
Most frequently this code is set by someone revving up an unloaded cold engine (i.e. lets hear that exhaust/intake). The system is temperature specific. Let the car come down to ambient and then reset the ECU. Warm it up and see if the code still shows (if you are using either a PGM Scan Tool or OBD Explorer make sure you request a new set of data!). If you still get a MIL light drive around for a mile or two....it may clear itself. If it does not the go under the drivers side bumper just behind the fake intake and check the wiring. The air pump has a large hose coming from it so it's easy to find (it's location is also the reason the CAI guys go to the passenger side).

If it were me I would reset the ECM and find out if the codes are real or were induced by abuse of the emission system.
Reset:
1)Turn the ignition key off
2)Remove the No. 25 BACK UP fuse (7.5 A) from the under fuse relay box for 10 seconds.
