If you mean idle speed control valve ISCV which allows the right amount of air pass the throttle flap when the engine is idleing so it dose not stall then the only thing you can do is clean the inside of it the best you can and remove the oily **** that builds up inside and stops the solidnold moving. If this fails a new one is the only option.
If you also mean a vaccume swithch which opens and closes to allow vaccume to operate different components and has at least 2 rubber pipes attached there is no fix as they are seal units. Just check the pipes are not spilt or fallen off. hope this helps

Who told you these things? Autozone? Those guys don't know their kester from a hold in the ground about electronic engine control systems.. This is a very expensive part, have a qualified technician diagnose the problem and replace the correct part or make the right repair.
With melting parts that could be an issue with the diverter valve, but the electrical issue adds a new complication to the deal. I'll have to admit, my experience with SMOG systems is limited. I don't know exactly how that shop did your electrical test, but unless they did a live test where they measured how much current draw you had during operation of the pump, I don't know how they could draw any conclusions as to if the pump is good or bad. The electrical solenoid as I understand it, is not part of the pump and is there to divert the air to the proper location and then closing during deceleration to prevent backfire. I would think since you are having issues with the fuse and melting hoses, that your diverter valve/solenoid is the issue. If none of this information is useful to you, I certainly wouldn't hold it against you to ask for a refund for this service and seek help from another member. If the information is useful, I am glad, and ask that you don't forget to rate.
YEP EASY FIX CHECK FUSES TO AIR PUMP VACUUM SOLENOID.CHECK VACUUM HOSES AND VACUUM SOURCE TO THE AIR PUMP VACUUM SOLENOID .THE AIR PUMP VACUUM VALVE SOLENOID IS NORMALLY CLOSED NO VACUUM IS APPLIED TO THE CHECK VALVE. WHEN THE PCM ENERGIZES THE SOLENOID BY COMPLETING THE CIRCUIT TO GROUND. THE VALVE OPENS VACUUM IS APPLIED TO THE CHECK VALVE. THE CHECK VALVE OPENS AND AIR FLOWS THROUGH THE TUBE INTO THE EXHAUST MANIFOLD. THREE THINGS WILL CAUSE SECONDARY AIR PUMP PROBLEMS.THE SECONDARY AIR PUMP IS BAD.OR THE AIR PUMP VACUUM SOLENOID NOT GETTING VACUUM OR POWER.OR THE CHECK VALVE TO EXHAUST MANIFOLD NOT OPENING.IF YOU HAVE FAULTY SECONDARY AIR PUMP IT WILL MAKE SQUEALING NOISE AIR PUMP GETTING READY TO LOCK UP.
hi, this two sensor are really important,The
Torque Converter Clutch, (TCC) or swithc is what actually causes the TCC
to engage and disengage. When the TCC switch receives a signal from
the ECM, it opens a passage in the valve body and hydraulic fluid
applies the TCC. When the ECM signal stops, the solenoid closes the
valve and pressure is vented causing the TCC to disengage. If the TCC
fails to disengage when the vehicle comes to a stop, the engine will
stall. The Air intake temp is for the engine performance, it helps to control fuel flow,and air flow. and about the location of the torque converter it should be on the transmission but dont know exactly where and the intake air it should be on the trottle body or on the intake maniful but same thing don´t know exactly where, i wish i can help you to locate them but i don´t usually work on hyundai (no offence), but for best result go to a local parts sotre and buy a Haynes repair manual for your car i should not cost you more than 20 dollars, hope this helps you.
First, you should have a warning light telling you it is not working. There is a switch for the air suspension underneath the glovebox-right hand side or in the rear hatch area on the left panel..make sure it's on. If all 4 air bags are deflated it could mean the air pump or actuator is malfunctioning.
Being a 2006 BMW, I don't know if you really want to tear into the dash compartment. Your AC is working fine, the problem with the unit is your heater control valve under the dash is faulty. you cant fix it but replace it the cost with singlesolenoid 85 bucks and dual solenoid is 172 buck; your would have two because your car equip with his and hers climate control; without proper tools to work on the car taking the dash apart is a task especially you have to know every bolt location. The unit is not adjusting the valve like it suppose to. The valve work like and normal valve, same as your faucet at home on or off. the valve is not shutting off fully due to solenoid faulty or the valve it self is stuck,jam or not sealing and that is the reason why you still getting warm air. I can assure you if you turn the ac button off and let the fan run only you will get nothing but hot air, the air seem warm because is mixing with with the cold air from your evaporator. hope that help some, good luck
it's on the throttle body. Here's a Quest with same 3.0L engine. These often need cleaning with carb or throttle body cleaner
Idle Air Control (IAC) Valve
When the engine (6007) is running but not at idle, the throttle valve controls the amount of air admitted into the engine. The powertrain control module (PCM) (12A650) increases the fuel injection output in proportion to the increased airflow to achieve the appropriate air/fuel ratio.
During idle, the throttle valve is almost fully closed. It is therefore necessary for the idle air control system to supply air for combustion during idle. The idle air control (IAC) valve allows a metered amount of air to enter the intake manifold (9424). The camshaft position (CMP) sensor detects engine speed and sends a signal to the PCM. The PCM sends a duty cycle (On/Off) signal to the IAC valve which allows additional air to enter the intake manifold. Air is added by the IAC valve to maintain the set lowest idle speed at which the engine can operate.
The idle speed adjusting screw allows adjustment of the airflow into the intake manifold.
Fast Idle Control (FIC) Solenoid
The fast idle control (FIC) solenoid helps maintain a constant idle speed while the air conditioning is operating. When the air conditioning is turned on, the front climate control panel sends out two signals. One signal is sent to the powertrain control module (PCM) (12A650) to engage the A/C compressor (19703). The second signal is a ground signal sent to the FIC solenoid relay, to engage the FIC solenoid. The FIC solenoid supplies additional air to adjust the increased engine load.
This sounds like the idle air control valve. This valve sits on the inlet manifold and basicly regulated the flow of air for tickover( or idle). The usual operation of this valve is, when the engine is running at high speed the valve will be closed, when the engine comes down to idle, the main throttle butterfly will shut as you lift your foot off the pedal. The idle valve will open and give a small amound of air to the engine, just enough to run it at idle speed. These valves can stick open, therefore letting air in when the throttle is open, giving the engine too much air. WD40 is only a temporary repair untill it jams again. Best course of action is to have part replaced.
