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

Secondary Injection System problem?


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.

TEE fiting that join hoses on smog pump keeps melting every few miles, Already have changed smog pump with new one from dealer, and problem came right back. I was told then that problem was electrical...


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.

My secondary air pump for my exhaust system is no good causing my car to fail inspection is it easy to fix


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.

WHEN I START THE CAR AND ACCELERATE AUTOMATICALLY THE CAR GOES OFF I HAVE DONE SCANING OF CaR THEY TOLD 2.NOS. OF PART TO REPLACE 1.TORQUE CONVERTER SWITCH 2.INTAKE AIR TEMPERATURE SENSOR . I WANT...


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.

How many fuel pumps does a 93 saturn sl2 have? ours will not idle. we have replaced the fuel filter, but are curious about the fuel pump or a possible clog in the fuel line. if we keep our foot on the gas,...


Clogged line is not in reality, It only has 1 fuel pump, And if it runs with foot on gas its not bad. Your issue will be more likely a vacume leak or idle air motor, And in my experiance its the Idle air motor, It has 2 screws and very easy to change,

My licoln navigator front suspension is not working..stays deflated


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.

Replacing Idle Control Valve on 97 Pathfinder, need help!


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.

Kia Sportage 2003 - Solenoid Valve


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.
