my dad has a 2003 taurus and just got a cel. i used my xcal2 to read it, and it says P1506, how can i find out what this code means.
thanks guys

just google "P1506 ford obd2 codes"

DTC P1506 is set when the PCM detects the engine idle speed is greater than the desired rpm. This is most commonly caused by a dirty or bad IAC valve. Cleaning the throttle body will, most likely, cure this problem.

thanks i will try that that and see what happens
