Standard Ignition TX81 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for Chrysler and Dodge

Standard Ignition TX81 is an engine coolant temperature sensor built for accurate temperature input to the engine management system. It uses a bolt-on attachment, a rectangular female connector, and a 2-blade male terminal layout for reliable electrical connection in the correct application.

Compatible With Chrysler, Dodge, Jeep, Plymouth, and Mitsubishi vehicles across a broad range of 1995-2008 model years, including Dodge Dakota, Ram 1500, Jeep Grand Cherokee, and Chrysler Neon applications. The TX81 is a direct-fit temperature sensor solution for vehicles that rely on consistent coolant temperature data for fuel and drivability control.

Key Features

• Bolt-on engine coolant temperature sensor design
• Rectangular 1-connector, female housing
• 2 male blade terminals for secure signal transfer
• Brass casing construction for added durability
• End-of-line tested for functional performance and linearity
• Built to maintain dependable connection quality in engine management systems

Detailed Description

Standard Ignition TX81 is engineered as an OE-style engine coolant temperature sensor for Chrysler, Dodge, Jeep, Plymouth, and Mitsubishi platforms. It is used to report coolant temperature to the vehicle computer so the system can manage fuel delivery, idle strategy, and other temperature-based engine functions. This part cross-references Mopar 56027873 and Beck/Arnley 158-1467 for the same application. The TX81 is a strong match for drivers searching for a Dodge Dakota coolant temperature sensor, Jeep Grand Cherokee temperature sensor, or Chrysler Neon engine coolant temperature sensor replacement.

What It Helps Address

• Incorrect coolant temperature readings
• Hard starting when the engine is cold
• Rough idle related to temperature signal errors
• Check engine light concerns tied to coolant temperature sensor faults
• Fuel control issues caused by inconsistent sensor output

Installation Notes and Tips

Verify connector shape, terminal style, and attachment method before installation. This TX81 uses a rectangular female connector with male blade terminals and a bolt-on mount, so the replacement should match the original sensor configuration. Confirm vehicle application by year, make, and model, especially on 1997 Jeep TJ and 1997 Jeep Wrangler listings that require a rectangular connector.

Quality Assurance

Standard Ignition manufactures these temperature sensors with brass casings and tests each unit for function, environmental durability, and linearity to meet engine management expectations. The TX81 is built to deliver consistent electrical performance in the listed Chrysler, Dodge, Jeep, Plymouth, and Mitsubishi applications.
