My 2001 Aurora's check engine light came on and the codes are P0107 map/bavo Circuit Low Input and P0410 Secondary Air Injection System Malfunction
Does anyone know where these are located so I can change them. And what do they do?Thanks

P0410 is usually a blown 50 amp fuse in the emissions control. Take a look inside your fuse box. Easy, quick, cheap fix.
The other one sounds more complicated. It's not related. Looks like you'll be replacing either the MAP sensor or the PCM (powertrain control module). However, you should first check for a short to ground. The sensor is one of the millions that send a reading to your PCM (this one reads barometric pressure) when you start the car to tell it how to operate the engine given certain climatic conditions. Hope this helps!

Hope this helps! I think im with you..Just look for a short? And does this stuff effect my car alot? Would it make a difference in how the car rides/idles?

I can't answer, as I've never actually experienced the problems in question. However, if you didn't notice it before you got the official word from the code reader, then they possibly aren't that bad. You'll have to make the call on that one. Good luck!

""" manifold absolute pressure: (MAP) manifold pressure measured on the absolute pressure scale, an indication of engine load. At sea level, MAP = 1 bar (14.5 psi)
/a> manifold absolute pressure sensor: (MAP) A sensor which monitors the engine's intake manifold pressure and transmits the data to the engine controller. A pressure-sensitive disk capacitor used to measure air pressure inside the intake manifold. The Map sensor sends a signal to the computer which uses this information to determine load conditions so it can adjust spark timing and fuel mixture. Also called manifold pressure sensor or pressure differential sensor """
The map sensor code could be cause by something as simple as a vacuum leak. check to be sure all hoses (especially PCV valve) are connected and in good condition.
Are you having drivability problems??

The car seems to be driving fine. When im stopped at a light it seems like it is running a little rough...Thats why I want to try and fix everything that is wrong with the car.I appreciate all the help I am getting. And I would like more help so my car can start running normal. Thanks...Ill check the hoses. If you can think of something else please let me know.
