Perhaps a google search "Cadillac P0410" , a search of on line Cadillac forums, or Autozone have some popular workshop manuals for free on line once you register (for free) on their website http://bit.ly/autozone_repair_info .There is a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://bit.ly/alldata_repair_manuals or try http://bit.ly/mitchell_repair_manuals_online and get an online repair manual subscription.
Can you look in your Haynes manual and tell me what the code PO419 relates to. I believe it is the secondary air injection code. My check engine light is on, and I have replaced the airflow sensor. It's a 2005 Chrysler Sebring. I do smell antifreeze, which indicates Heater core issue. I don't know what to replace?
I just bought my car and the service ingine light came on.I had it read and it came back with secondary air injection system malfunction.Does anyone know what that means? And estimate repair cost? Thanks..Mr.Lee
