Standard Idle Control Valve Review
Even when your vehicle is halting at a red light or temporarily parked, there are still components that make it possible for your engine to operate. One such part is the idle control valve. Also called an idle air control valve, this component that is located above the throttle body regulates the amount of air that circulates in the engine at idle. Without this part, your engine will not have a stable rpm and will experience rough idling. Of course, parts that are responsible for air regulation need to be kept in their best shape in order to have a well-functioning engine. When the IAC valve goes bad, make sure to replace it with one that can properly regulate air flow around the throttle. Standard is one brand that you might try, but before buying its product, let us first see if its IAC valve will be a good replacement.

We tested this component on a Toyota Corona and a Nissan Versa, and here is what we have to say:
- The component fit directly to the mounting location above the throttle body of the Corona. The entire procedure, which included removing the old unit, took only about forty-five minutes.
- The five-year-old Corona had been experiencing episodes of problematic rpm regulation. But when we installed the new IAC valve, the engine’s rpm seemed to have stabilized. Idling behavior became generally better.
- During the drive with the Corona, the check engine light did not illuminate to indicate any trouble with air flow into the engine.
- The installation instructions did not indicate that it was highly necessary to purchase a new gasket when replacing the idle air control valve. The gasket of the Corona and the Versa had expanded due to pressure, so it did not fit when we tried to reseal the IAC valve. The tip about the replacement gasket would have prevented the hassle of buying it without notice.
- The installation instructions did not mention that the unit would not be compatible with an SOHC engine, which was what the Versa had. The connector on the Versa’s old IAC valve was pointing to the side, while that on the replacement valve was pointing straight up.
The price of this product is somewhere on the expensive side of the spectrum. However, it is generally a good unit that performs accordingly and comes with a confidence-grabbing warranty. Just make sure that you determine whether you have an SOHC or a DOHC engine in order to avoid fitting hassles. Of course, purchase a new gasket at the same time.
