My a4 2.7 was running good and out of the blue stalled and wont run. i checked and was not getting spark. The only code that came up was a P1509 idle speed sensor aux input, will this cause no spark and how do i fix it? Thanks for any replies really appreciate it!

 

p1509 Idle Air Control Circ. Electrical Malfunction. most likely cause is the idle air control motor shorted out, it will not allow the car to start. replace it.

 

Thank you i really appreciate the reply
