412 is something about the secondary air injection system
410 secondary air injection system
403 system fault exhaust
this is on my 04 she has about 41,000 and I am her only owner.
I have noticed that the check engine light may come on after a fast acceleration. the check engine light will come on and then go out a few days later.
any ideas?
This is not a serious problem, the air pump has a problem. You would not pass the Drive Clean test if the light is on and you have the problem stored in the memory.
It is all about pollution and this system injects air into the exhaust to warm up the cats faster.
When you turn on the car when its cold, get out fast and listen for a minute with the hood up. After about 30 seconds or so you should hear a noise disappear. If it does the pump is working correctly at that time, the hard part is when the pump is not working or is working all the time. In this case you will not hear any change.
Problems arise when the wires that go to the pump are not making contact properly or the solenoid in the RCM is stuck on or sticks once in a while.
As you seem to have a problem when you act like Mustang Sally or the Li'l old lady from Pasadena (which ever fits) I would suggest you lay off the gas.
