dont take soo much in consideration after you have make all this things, some time is on only for any wire faulty, or a shrt electrical arc in any place in wire system. ask auto tap mechsnics for this maybe they have similar case before.

SOURCE: IAC control valve. Locato\ion 2002 ford escape

If it's not idling and has problems starting, it's probably the IAC motor. It's located on the throttle body. Follow the airfilter box all the way to the engine, where the rubber flex hose attaches. The throttle body should be the first aluminum part you come to. Attached to the side you'll find small little aluminum part with a small wire harness attached. Unplug it, take the IAC motor off and clean inside with carb cleaner. This should fix the problem with the idle.

SOURCE: how do i replace iac valve on 2001 ford escape

The IAC vavle is located behind the EGR valve on the driver side of the motor. You will disconnect 2 hoses and unplug the wire harness from the system. The unit will come right out. Just make sure that the hoses you take off go back in the same place. Also make sure that you have the negative battery wire disconnected. I had this same issue on my 2001 Escape, had to replace both the EGR and IAC so check both carefully.

There is a large vac line coming straight down from the throttle body that goes to the PCV system. See if it has a hole in it. It is likely sucking air.

Where is IAC system on my ford Taurus


The Idle Air Control (IAC) valve will be a solenoid mounted on the side of the throttle body. The throttle body is the butterfly valve that your throttle cable goes to. Air goes through the throttle body from your air filter.

My ford taurus SE 1999 have 3 codes P1504, P1507 and P1131


DTC Description Possible Causes Diagnostic Aides P1504 - Idle Air Control (IAC) Circuit Malfunction This DTC is set when the PCM detects an electrical load failure on the IAC output circuit.
  • IAC circuit open
  • VPWR to IAC solenoid open
  • IAC circuit short to PWR
  • IAC circuit short to GND
  • Damaged IAC valve
  • Damaged PCM
  • The IAC solenoid resistance is from 6 to 13 ohms.
    • IAC valve stuck open
    • Vacuum leaks
    • Failed EVAP system
    • Damaged PCM
  • The IAC solenoid resistance is from 6 to 13 ohms.
P1507 - Idle Air Control (IAC) Underspeed Error This DTC is set when the PCM detects engine idle speed that is less than the desired rpm.
  • IAC circuit open
  • IAC circuit short to PWR
  • VPWR to IAC solenoid open
  • Air inlet is plugged
  • Damaged IAC solenoid
  • Damaged PCM
  • The IAC solenoid resistance is from 6 to 13 ohms
  • Disconnect IAC valve and look for no change in engine rpm as an indication of a stuck or damaged valve
P1131 - Lack of HO2S-11 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.
  • Electrical:
    • Short to VPWR in harness or HO2S
    • Water in harness connector
    • Open/Shorted HO2S circuit
    • Corrosion or poor mating terminals and wiring
    • Damaged HO2S
    • Damaged PCM
  • Fuel System:
    • Excessive fuel pressure
    • Leaking/contaminated fuel injectors
    • Leaking fuel pressure regulator
    • Low fuel pressure or running out of fuel
    • Vapor recovery system
  • Induction System:
    • Air leaks after the MAF
    • Vacuum Leaks
    • PCV system
    • Improperly seated engine oil dipstick
  • EGR System:
    • Leaking gasket
    • Stuck EGR valve
    • Leaking diaphragm or EVR
  • Base Engine:
    • Oil overfill
    • Cam timing
    • Cylinder compression
    • Exhaust leaks before or near the HO2S(s)
A fuel control HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S.

Ford taurus 2002 diagnostic says p0191 and p1506 light comes on check engine car runs then after time it will die off. had a button in back trunk to switch if car gets bump thought might be cause started...


Hello! the P1506 is indicating a defective Idle Air Control (IAC) valve,,,P0191 is indicating a fuel rail pressure sensor (FRPS) fault...I suspect a cause and effect on the two codes...
Cause= IAC...Effect= FRPS....See photo below...Remove and clean with throttle body spray cleaner before you purchase a new one...It may only be blocked with carbon...Guru..Saailer

I have a 2002 ford taurus. check engine light is on. Auto Zone did a scan today and the error code was p1507 can you please tell me what i need to do to fix this problem.


possible problems

Vaccuum leak
failed IAC valve
open or short
air inlet plugged

P1507 means "Idle Air Control Underspeed Error". It can be most commonly caused by a vacuum leak, a damaged Idle Air Control (IAC) assembly or a stuck IAC valve that needs cleaning. Essentially, your engine isn't idling at high enough according to your computer's programming parameters. Many times this shows up in colder weather as you try and start your vehicle. It will usually die unless you put your foot on the gas pedal and raise the RPM's. I have also read where a clogged air filter might be the problem. I would try cleaning your IAC valve first.
