Detailed Product Description

The Standard Ignition TX73 sensor is engineered to measure the temperature inside the engine intake manifold accurately. Its brass body combined with plastic components offers durability and resistance to heat and corrosion. The sensor uses a screw-in attachment method with a 10mm x 1.00 thread size, ensuring a secure and precise fit in the intake manifold. The electrical connection is facilitated by a single female round plug-in connector with two male pin terminals, designed to maintain a stable and consistent signal to the engine control unit (ECU). This sensor is compatible with various Saturn models including SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2, making it a reliable replacement part for maintaining proper engine function.
