How to Check, Remove, Bench Test, and Install the Idle Control Valve on a Toyota Supra?

Start the engine and then turn it off, verifying that the Idle Control Valve makes a clicking sound immediately after the engine stops; if it doesn't, remove and bench test the valve. Disconnect the cable from the negative terminal of the battery, ensuring to check for any anti-theft system in the stereo before detaching the cable. Unplug the Idle Control Valve electrical connectors, then detach the coolant by-pass hoses and air hoses from the Idle Control Valve, plugging the coolant hoses if coolant begins to flow out. Remove the Idle Control Valve mounting bolts, the valve, and the gasket, and for turbo models, also remove the seal washer and check valve from the air intake chamber. Using an ohmmeter, measure the resistance between terminal B1 and S1 or S3, and between B2 and S2 or S4, comparing the measurements to the specific resistance values; if they are outside the specified range, replace the Idle Control Valve. Apply battery voltage to terminals B1 and B2 while grounding terminals S1, S2, S3, S4 in sequence to verify that the valve moves toward the closed position, and then repeat the process grounding in reverse order to check for movement toward the open position; if the valve does not perform as expected, replace it. For installation, reverse the removal steps, ensuring to install the check valve and seal washer in the air intake chamber first for turbo models, and use a new gasket on all models. Finally, check the coolant level and add as necessary to reach the desired level.

Toyota Supra Idle Control Valve

Idle Control Valve (IAC) is one of the parts that help in boosting up various Toyota Supra models especially the A70 and A80 generations. This is an electrically operated devise mainly employed to govern the idling speed of the engine by controlling the amount of fresh air that is admitted ahead of the throttle plate to maintain smooth running and to avoid stalling during changes in load. The Idle Control Valve is able to control the airflow with the help of linear servo motor to meet the necessary standards of the idle speed so crucial for fuel efficiency and safe operation. This specific intercooler, Toyota Supra IAC, has a rather rigid construction and fits various versions of the Supra. Dirt build-up on the Idle Control Valve is another common problem that affects consistent idling, therefore, should be taken for service activities. Due to the consistent quality of its product, the Idle Control Valve of the Toyota Supra has become reputable in the automotive industry especially in relation to performance and durability. Added attributes, specifically its compatibility with the engine control unit (ECU) make it even more attractive, thus, the Toyota Supra guarantees a thrilling ride. Thus, the Idle Control Valve can be deemed a significant component that serves as the key to the legendary status of the Toyota Supra in the automotive industry.
