    How to fix fault code P1507


    Possible causes
    - Faulty Idle Air Control (IAC) valve
    - Idle Air Control (IAC) valve harness is open or shorted
    - Idle Air Control (IAC) valve circuit poor electrical connection
    What does this mean? Tech notes
    The P1507 code means that the engine idle is out of factory specification. Sometimes the Idle Air Control (IAC) may have carbon built up. Disconnect the car battery, remove the valve, clean, re-install valve, and drive the vehicle for about 5 minutes with the headlights and A/C ON to get the idle relearned.
    If the problem persist, the IAC valve may need to be replaced.

    How to increase the idle speed?



    • The idle is controlled by the IAC valve. there is no way to adjust it, it is computerized. On the side of the engine, by the intake. Look for the cable on the IAC valve, remove the connector and remove the screws. Now pull the IAC out and clean it real well with brake clean and let it dry for a couple minutes. This often takes care of the idle issue but if it does not then you might want to replace the IAC.

    • If you have any comments please feel free to leave them here.
    • Hope this helps and thank you for using FixYa.

    When i turn on the ac the idle goes low and the the car vibrates. When i turn off the ac the car stop vibrating.



    Operation

    The Idle Air Control (IAC) valve controls the amount of air that bypasses the throttle valve, which controls the engine idle speed. The IAC valve consists of windings, an armature, a return spring, and a rotary slide. The engine control module (ECM) pulses the voltage to the winding, the opposing forces on the armature by the return spring cause it to maintain a fixed position, adjusting the amount of bypass air to maintain the correct idle speed.


    Removal & Installation

    1. Turn the ignition switch to the OFF position.
    2. Disconnect the idle air control valve harness electrical connector.
    3. Using a suitable tool, remove idle air control valve.
    4. Installation is in reverse order of removal.


    Testing

    Checking Idle Air Control Valve (IAC) Triggering

    1. Check IAC valve is electrically OK.
    2. Slide up boot on the IAC valve connector.



    0900c152801c00a1.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. IAC Connector

    1. Use scan tool 'Output Diagnostic Test Mode' function 03 to trigger the IAC valve - N71.
    2. Connect VAG 1527B voltage tester, or equivalent, between terminal 1 and engine ground (GND). Voltage tester must flash.
    3. Connect VAG 1527B voltage tester, or equivalent, between terminal 2 and battery positive voltage (B+). Voltage tester must light up.
    4. If specified results are not obtained:
      1. Connect VAG 1598/19 test box, or equivalent, to ECM harness connector.
      2. Check the wiring between harness and connector terminal 1 (in engine compartment) to test box socket D11 . Then check the wiring between harness connector terminal 2 and test box socket D9 using wiring diagram. Repair as necessary.
      3. If the wiring is okay, but triggering still does not occur, replace the ECM.
      4. If the triggering signal and the wiring are okay and the valve does not react, replace the IAC valve.


    Checking Mechanical Function
    1. Remove the idle air control (IAC) valve.
    2. Visually check the surface of the rotary slide (arrow) for signs of wear.



    0900c152801c00a2.jpg enlarge_icon.gifenlarge_tooltip.gif

    Fig. Showing the IAC Valve

    WARNING Do NOT check for ease of movement by prying on the rotary slide with a screwdriver or other tools that could cause scratching or other damage.

    1. Reconnect the IAC valve, while still removed, to the harness connector.
    2. Use scan tool 'Output Diagnostic Test Mode' function 03 to trigger IAC valve - N71.
    3. Check whether rotary slide moves freely from stop to stop.
    4. If there are signs of scoring, or if the rotary slide does not move freely in both directions, replace the IAC valve.
    5. If the IAC valve does not respond (not triggered) during the Output Diagnostic Test Mode, check triggering.

    Resistance Test
    1. Remove the idle air control valve harness connector.
    2. Use a suitable Digital Multimeter (DMM) to measure the resistance between the 2 terminals of the idle air control valve.
    3. The correct measurement should be 7-11 ohms. If not, replace the idle air control valve.


    NOTE At room temperature, the resistance value will be lower. The resistance value will be higher if the Idle Air Control (IAC) valve is measured at under-hood operating temperatures.
    1. Reconnect the idle air control valve harness connector.
    2. The idle air control valve should hum and vibrate slightly when the ignition is turned 'ON'. If not, the ECM or harness may be defective.

    Testing with VAG1551:
    1. Remove the idle air control valve harness connector.
    2. Connect the VAG 15278 LED tester to terminals 1 and 2 of the harness connector using the jumpers from VW 1594 adaptor kit.
    3. Turn ignition ON, perform steps from output DTM (Diagnostic Test Mode) to activate the IAC valve (N71) LED tester must blink.
    4. If tester does not blink, check wiring using VAG 1598 pin out box, electrical checks, step 26. Repair as necessary.
    5. If wiring is okay, replace the ECM.
    6. If LED tester blinks but the IAC valve does not operate, replace the IAC valve.

    may just need cleaning with carb cleaner.

    here is 1996, oldest I have:

    Section 03-14: Engine Controls, Electronic 1996 Taurus, Sable Workshop Manual
    REMOVAL AND INSTALLATION Idle Air Control (IAC) Valve Removal
    1. Disconnect battery ground cable (14301). Refer to Section 14-01 .
    1. Disconnect the engine control sensor wiring (12A581) from the idle air control valve (IAC valve) (9F715) at the idle air control valve electrical connector.
    1. Remove the two idle air control valve retaining bolts.
    1. Remove the idle air control valve and idle air control valve gasket.
    Installation
    1. NOTE: If scraping is necessary, be careful not to damage idle air control valve gasket surfaces, or drop material into intake manifold (9424) or throttle body (9E926) (depending upon application).

      Clean idle air control valve gasket mating surfaces.
    1. To install idle air control valve, reverse Removal procedure.
    1. Tighten the idle air control valve retaining bolts to 8-12 Nm (71-106 lb-in).

    1992 Honda Accord wont start when cold out Fires but wont stay running


    this could possibly be an iac or idle air control valve issue. the iac valve controls the amount of air that bypasses the throttle body in order to maintain proper idle, and is mounted on or very near the throttle body on the intake manifold. check the connector to ensure it's tight and the connections are clean, not corroded. i'd recommend replacing the iac valve.
