hey guys car is running a p4011 secondary air pump
replacement on the pump shows huge dollars, it sounds like its working properly when i start the car every day any advice anyone experience this?

 

Same problem here, i can also hear it on and off sometimes etc. I dont mind cel light just dont have it blinking. The Euro guys have a saying " if the cel light is off , we have a problem"... lawls

 

Your air pump contactor is likely going bad. Replace it before it overheats the airpump.

I have the part if anyone wants to buy it

 

I believe that's the code for incorrect flow rate. Your pump could be melted already or there might be a problem with the hoses

 

book shows codeP0411 secondary air injection system incorrect flow. Note there is no code P4011 only P0411.Check hoses cracks leaking plugged up .Check for vacuum at at the hose that goes onto air control valve. Make sure car is warm when checking. Next if all looks ok you need to check the air control valve vacuum control solenoid. It could also be the wiring to it check no. 6 fuse under the dash make sure its not blown. That's roughly what book says....

 

i had the same problem, my problem was a cracked and dirty hoses.

 

now, was due to intense speed or vigorous stopping power?

 

LOL HAHAHAHAHAHA typo win!!
