Where is the IAC on my 2002 Toyota Echo?


The IAC is on the bottom of the throttle body and has a hole in the bottom of the throttle body that lets air into the IAC. YOu do not have to remove it, if you do remove it the throttle body would have to come off and a new gasket would be required. Usually spraying through with throttle body cleaner will clean the IAC so it functions properly.

About your P0505 faut code, The IAC (Idle Air Control) valve controls the idle speed of the engine. At idle the throttle plate is closed, of course. The IAC is computer controlled and allows only a certain amount of air around the throttle plate. This metered air controls the idle speed. The IAC has a "plunger" or "shutter" that moves to open or close the bypass air passageway. The more air the IAC allows around the throttle plate, the higher the idle. The PCM (Powertrain Control Module) uses the IAC valve to keep the idle speed correct with varying engine demands. Can be a three or four wire sensor depending on the model.
The PCM monitors voltages of the IAC circuits and if it detects an incorrect voltage on one or more of the IAC motor circuits it will set P0505. NOTE: Problems with the IAC would only be noticeable at idle or when throttle is closed.

Symptoms may include:MIL (Malfunction Indicator Lamp) illuminationEngine stalls and may not idle unless throttle is depressedIntermittently stalls when letting off the throttleEngine may idle too high

Potential causes of an P0505 code include:IAC motor connector is damaged (check connector and pins for damage, and moisture)One or more IAC circuits open or shorted to groundOne or more IAC circuits are shorted to voltageIAC has failedPCM has failed

Possible Solutions:This should be a fairly straightforward diagnosis. Start by clearing the fault codes. Then unplug the IAC and start the engine (This may cause other IAC codes to set. Just ignore them for now). If the P0505 code doesn't reset, replace the IAC. It is internally shorting one of the IAC circuits. If the code DOES return after unplugging the IAC and starting the engine, then you know it isn't the IAC motor. Visually check the wiring harness all the way back to the PCM. You may need to visually inspect the harness by removing all the insulation off the wires. It is possible that the wires could be shorting to eachother or to other wires in the harness.
If there are no wiring problems, and the code keeps returning with the IAC unplugged, you can check the PCM by removing the IAC wires from the PCM connector (or clipping the wires in a location where they can be repaired easily) and then start the engine (If you're not sure, don't do it. Take it to a qualified professional). Now if the code doesn't reset there is a problem with the wiring. Check for continuity on all the IAC wires. Any resistance points to a problem. Check for voltage on any(At this point there shouldn't be any voltages on the wires because they're clipped at one end and unplugged at the IAC). Repair as necessary. But if the P0505 code DOES reset after removing the IAC wires from the PCM connector(or clipping them), replace the PCM, there's a problem internally on the IAC control circuit.

Hope this helps.

That is idle air control (IAC) system malfunction,it's causes may include:
IAC motor connector is damaged (check connector and pins for damage, and moisture);
One or more IAC circuits open or shorted to ground;
One or more IAC circuits are shorted to voltage;
IAC has failed; or PCM has failed
You can clearing the fault codes. Then unplug the IAC and start the engine. If the P0505 code doesn't reset, replace the IAC. It is internally shorting one of the IAC circuits. If the code DOES return after unplugging the IAC and starting the engine, then you know it isn't the IAC motor. Visually check the wiring harness all the way back to the PCM. You may need to visually inspect the harness by removing all the insulation off the wires. It is possible that the wires could be shorting to eachother or to other wires in the harness.

Hope this helpful.

Labored start and runs while accelerator is pressed. Shuts off immeditely if you release the accelerator.


Check to see if the IAC (idle control valve) is stuck in the bore of the throttle body. you can do this by;

remove the air snorkel from the throttle body.

locate the IAC, it will be round, sometimes silver or gold metal color, an have 4 or five wires on the connector.

You should see a passage in the throttle body near where the IAC is located. look in that passage and see if you can see the pintle of the IAC.

Use a small screwdriver and gently push the pintle of the IAC towards the IAC body. Once it is moved back try starting. Be ready to turn the engine off if the idle goes to high.

If the idle goes up tan remove the IAC (usually two torx screws). Carefully inspect the pintle. If the head looks worn replace it. If it is covered in carbon clean it with carb spray. Also clean out the passage with carb spray. Reinstall the IAC (new or used). Cycle the key a couple of times with out starting the vehicle. This will allow the pintle to move closer to the idle position. Start the vehicle.

Let me know if that works or if it doesn't. I'll be happy to help you further if needed.

Computer code p0505 -running at high idle


Hi, not sure which engine you have so I can't be precise, but here is what I recommend. Remove the idle air control valve and check the valve seat for blockage. If dirty, clean both the passages and the valve, reinstall and see if that resolves the code. If it isn't blocked or dirty, run the tests below using a volt/ohmmeter. The primary test to run is step 8. If the valve fails step 8, replace the valve. If it passes, then check the PCM reference voltages in step 7. Let me know if you have questions.

TESTING Conclusive testing of this component requires the use of special, factory-supplied equipment and is not included here. The tests below will provide valuable information regarding condition of the IAC motor and require only a VOM.

  1. Ignition must be OFF .
  2. Disconnect the IAC motor connector.
  3. Disconnect the PCM harness connector(s).
  4. Measure the resistance of the four IAC motor wires between the motor connector and the PCM connector. Refer to the illustrations for wire colors.
  5. Resistance should be under 5.0 ohms. Replace any wire with a higher resistance.
  6. Check for resistance between each motor lead and ground. Replace any wire with resistance under 5.0 ohms.
  7. Remove the ASD relay from the PDC (location is shown on the underside of the PDC cover. Connect a jumper between cavity 30 and 87 . Turn the ignition ON . Measure the voltage at each of the driver wires. Voltage should not exceed 1.0 v.
  8. With the ignition OFF and the IAC and PCM connectors detached, measure the resistance between each driver wire and ground. Resistance must be above 5.0 ohms in each case.

REMOVAL & INSTALLATION
The IAC motor is located on the rear of the throttle body secured by two Torx® screws.

  1. Disconnect the negative battery cable.
  2. Remove the air cleaner assembly.
  3. Unplug the IAC motor connector.
  4. Remove the two mounting Torx® screws.
  5. Remove the IAC motor from the throttle body.


WARNING When the IAC motor is removed from the throttle body, do NOT extend the pintle more than 0.250 inch (6.35mm). If the pintle is extended more than this amount, it may separate from the IAC motor and the motor will have to be replaced.

To install:
  1. Install the IAC motor in the throttle body.
  2. Tighten the mounting bolts to 60 inch lbs. (7 Nm).
  3. Plug the IAC electrical connector in.
  4. Install the air cleaner assembly.
  5. Connect the negative battery cable.
