Standard Ignition TX1 Engine Intake Manifold Temperature Sensor

Engine Intake Manifold Temperature Sensor for GM Applications

Standard Ignition TX1 is an engine intake manifold temperature sensor built with a screw-on brass body, a round female plug-in connector, and a 3/8-18 thread size. It is designed for direct replacement service on a wide range of older GM, Jeep, Buick, Cadillac, Oldsmobile, Pontiac, Chevrolet, and GMC applications.

With tight thermistor response tolerances and factory testing, TX1 is built to deliver accurate temperature measurement and consistent sensor operation. This Standard Ignition TX1 is a practical choice for service work on vehicles such as the Chevrolet C10, GMC Jimmy, and Oldsmobile Cutlass.

Key Features

• Engine intake manifold temperature sensor for emission control service
• Screw-on attachment with 3/8-18 thread size
• Brass construction with gold finish and plastic connector housing
• Female round plug-in connector with male bullet terminal
• 12-volt electrical design
• Factory tested for consistent operation
• Standard Ignition TX1 cross-references Dorman HELP 74040 for the same application

Detailed Description

Standard Ignition TX1 is engineered for accurate intake manifold temperature sensing in emission-related engine management systems. The brass sensor body and controlled thermistor response help maintain proper signal output, while the OE-style connector layout supports straightforward replacement on vehicles that use a single-terminal sensor design. This part number is commonly searched for Chevrolet C10, GMC C1500, and Pontiac Grand Am intake manifold temperature sensor replacement needs.

Standard Ignition manufactures this sensor with in-process control from component selection through final assembly. The result is a replacement part built to meet service demands across a broad range of older domestic applications, including many 1980-1993 GM platforms.

What It Helps Address

• Incorrect intake manifold temperature readings
• Emission control fault codes related to sensor input
• Rough cold-start or warm-up behavior tied to temperature signal errors
• Driveability issues caused by a failing manifold temperature sensor
• Replacement needs for OE-style sensor service on older GM and Jeep vehicles

Installation Notes and Tips

Verify thread size, connector style, and vehicle application before installation. TX1 uses a screw-on mounting style with a round female connector and single bullet terminal, so matching the original sensor configuration is important. Clean the mounting area before installing the new sensor and confirm the electrical connection is fully seated after installation. Fits 1980-1985 Oldsmobile Cutlass, 1981-1984 Chevrolet C10, and 1981-1984 GMC Jimmy, among many other listed applications.

Quality Assurance

Standard Ignition states that its temperature sensor designs use tight tolerance thermistor response values for measurement accuracy, and each sensor is factory tested before release. That manufacturing control supports dependable operation across the listed fitments, including Chevrolet, GMC, Oldsmobile, Pontiac, Buick, Cadillac, and Jeep applications.
