P0505 means the whole Idle Control system, not only the IAM. Check all related sensors (i.e. crankshaft sensor). Check with a voltmeter direct at the connector of the IAM if you get any signal. Remove the IAM from the TB, connect him, let someone switch your ignition key to ON. The IAM need to drive in/out for a short time to find the right position. Hold the IAM near a hard part, that they cant drive out completely! If IAM works fine, check the fuel pressure, check and clean your TB ( if not done yet). If that doesn't work, come back again please

My jeep keeps stalling on me and the check engine light never comes on, people tell me it may be the fuel pump. i have been told it cant be hooked to compuetr because of the check engine light not com


A stalling problem doesn't have to turn on the check engine light . Try some basic thing's like cleaning the throttle plate (body) air passages for the IAC - idle air control valve . There are videos on youtube , also check for a vacuum leak !

My car died a couple of days ago when I was driving. The codes P0505 and P0123 appeared. I replaced the sensors and the car still won't start and P0505 was still showing up


the idle air control valve is on the throttle body below the throttle positioning sensor. To test first, use a test light on the connection coming to it with the vehicle running. Rev the motor and each terminal should make the light flash. In this case it is most likely the sensor. If they do not flash it is in the wiring or pcm
