Standard Ignition TX73 Engine Intake Manifold Temperature Sensor

Engine Intake Manifold Temperature Sensor Overview

Standard Ignition TX73 is an engine intake manifold temperature sensor built for accurate temperature measurement and reliable signal output. It is a screw-in, brass-bodied sensor with a round 1-pin plug-in connector and 10mm x 1.00 thread size for direct replacement service.

Compatible With select Saturn SC, SC1, SC2, SL, SL1, SL2, SW1, and SW2 applications, this TX73 sensor supports proper intake temperature monitoring on 1991-2002 Saturn models.

Key Features

• Screw-in mounting for direct installation
• Brass sensor body with brass and plastic finish
• Female round connector with 1 connector cavity
• 2-pin male terminals with plug-in connection
• 10mm x 1.00 thread size
• 12-volt electrical specification
• Standard Ignition TX73 replacement part

Detailed Description

The Standard Ignition TX73 intake manifold temperature sensor is engineered with tight thermistor response tolerances to support accurate temperature readings and proper sensor operation. Standard Ignition manufactures and tests these sensors at the factory to help ensure consistent performance before the part reaches the vehicle. This makes TX73 a practical replacement for Saturn SC1, SC2, SL, SL1, SL2, SW1, SW2, and SC models across the listed years.

This part cross-references Delphi TS10193 and Walker Products 211-1040 for the same application. The TX73 part number is also commonly referenced in service catalogs for intake temperature sensor replacement on Saturn vehicles.

Common Problems This Sensor Can Address

• Incorrect intake air temperature readings
• Check engine light related to temperature sensor faults
• Rough idle caused by inaccurate sensor input
• Fuel mixture issues from bad temperature data
• Hard starting or drivability concerns tied to sensor failure

Installation Notes and Tips

Verify the 10mm x 1.00 thread size, round connector style, and 2-terminal configuration before installation. Because this TX73 sensor is screw-in style, inspect the mounting port threads and sealing surface for damage or contamination before fitting the new unit. Confirm vehicle application by year and model, especially on Saturn SC, SL, and SW series vehicles.

Quality Assurance

Standard Ignition states that its temperature sensors are factory tested for performance and built under controlled manufacturing processes from component to finished part. TX73 is produced to support accurate sensor response and dependable operation in service.
