A P0411 code means: Secondary Air Injection System upstream flow. The air pump supplies oxygen to the exhaust manfolds during the first few minutes after the car is started. The PCM controls the EAM relay which controls the EAM air pump. Check: The 30 amp fuse label "Thermactor Pump Fuse." Voltage to the air pump should be battery voltage. The air hoses on the air pump for damage or blockage. Check the vacuum hoses to the one or two vacuum controled air diverter valves. PCM controled vaccum switch for deverter values.

That is a check engine light. It could be many things but it needs to be hooked to a diagnostic machine to determine what the problem is.
It could.It could.
It could be an emissions problem or a catalytic converter problem.
Check the engine. ===================================================== There is a problem with something that effects the emissions of the engine You need to have the vehicle scanned for any trouble codes to help diagnose and then repair the problem
check the thermostat or the fan motor could be the problem or a leak in radiator. just a thought
my transmission is not shifting on my 2005 Ford Taurus what could be the problem
If the check engine light is on, use a code scanner to find out why.
That varies with the problem. Could be immediate, or could take a week.
There could be several reasons for the check engine light to come on. You can take it to Advance Auto Parts or Autozone and if the check engine light is on they will hook it to their computer and tell you exactly what the problem is for free.
The check engine light on the Honda Pilot is an indicator that there may be a problem with the engine. This could be minor such as air or water in the gas tank or could be an indicator of something more serious.
The problem could be many things. With the check engine light coming on, it could be an internal issue in the engine, or broken engine mounts causing the vibrations. The shaking could also be caused by a separate issue from the engine, including a loose tire, or an out of balance tire, or bad suspension.
The problem to your 2007 tour glide check engine could be tensioners.
changed battery engine light stays on
The check engine light in a 2004 Toyota Tacoma can come on for many reasons. It could indicate an exhaust leak or a problem with the engine.
something that affects the emissions.
The check engine light indicates a problem in the engine controls or emissions system, have the computer codes read and you will know exactly what your car is trying to tell you.
It could very well be the catalatic convertor on the engine. Have it checked out.
Does the engine cooling fan come on at 230 degrees and turn off at 190 degrees? You could have a bad cooling fan, relay or sensor problem. If all of these check out you need to check for leaks and repair them. Also a stuck thermostat can be the bad apple.
check your hoses, there could be a vacuum hose with a leak causing this problem
The check engine light comes on when the ECU detects a problem with the emission system. To determine what the problem is you need to have the ECU scanned with an OBD2 scan tool. The code you retrieve will tell you where to start looking for the problem.
The thermostat would be the first thing I would check.
Trying to clear the check engine light in a Kia Sorento yourself is not recommended. The check engine light could indicate a serious problem and the car should be inspected by someone qualified.
It could be that you have not tightened the cap on your gas tank. Be sure to check the gas cap and see if its being properly tightened. That was the case for me a couple of times.
