Error codes P0803&P0410 help
 

Hello,
So I'm driving around today in my 98 SLK 230 and have the check engine light pop up on my dash :( I drop by my local auto store and they run the OBDII for me and come up with error codes P0803 (Upshift solenoid Circuitry Malfunction) and P0410 (Secondary Air Injector System). Now I have read about cleaning for the error P0410 but couldn’t find a clear post on where the items are located. And as for the P0803 I was unable to find anything at all. Any additional help without having to drudge over to the mechanics would be greatly helpful.
I am handy with tools and would like to take care of this myself; unfortunately I am unable to find any sort of shop book for my car yet.
Thanks,
J

p0410 actuation test, the O2 sensor reading must come down to 0.04 volts, it should read below 0.04 volts if every think perfect.
p0803 air flap switch over actuator actuation test see the switch over when testing. and the air pump must switch on when you do both test.

Many times the K40 power supply relay doesn't power the air flap actuator & of course if that flap is inop then the car will also fail the air injection test..

thanks for the quick replys... but i was on the way to work that night and the light turned itself off... should this concern me at all or let it go untill it lights up again?
oh and yes.. it still does light up before the car is started so the bulb isnt burned out at all.
