Car throttle body assembly sensor

The throttle body assembly on the 1986 Toyota Pickup with the 2.4L 22R-E engine is the gateway for air entering your engine. When you press the gas pedal, you're opening a plate (the throttle valve) inside this assembly, allowing more air in. The Engine Control Unit (ECU) then adds the right amount of fuel to match. This assembly is more than just a simple valve; it also houses the Idle Air Control (IAC) valve, which manages idle speed, and the Throttle Position Sensor (TPS), which tells the ECU how far the throttle is open. The proper function of all these integrated components is critical for smooth idling, acceleration, and fuel efficiency.

• For the 1986 model year, you MUST match your original throttle body's part number or visually match every vacuum port and connector; multiple variations exist.
• The most common failure is a high or erratic idle, usually caused by a faulty Idle Air Control (IAC) valve or its clogged coolant passages.
• After replacing the throttle body, you MUST perform a precise adjustment of the Throttle Position Sensor (TPS) using feeler gauges and an ohmmeter.
• New OEM throttle bodies are discontinued, making a verified, matching used OEM part the most practical replacement option.
