Standard Ignition TX133 Engine Coolant Temperature Sensor

Engine Coolant Temperature Sensor for GM Applications

Standard Ignition TX133 is an engine coolant temperature sensor built for accurate temperature reporting and reliable engine management. It uses a tight-tolerance thermistor response and a bolt-on design with a rectangular plug-in connector for direct service replacement on many Buick, Chevrolet, Cadillac, GMC, Saturn, Suzuki, Pontiac, and Saab applications.

Compatible With 2000-2017 Buick Enclave, LaCrosse, Allure, and Rendezvous; Chevrolet Traverse, Malibu, Camaro, Captiva Sport, Equinox, Silverado HD; Cadillac SRX, CTS, STS, and BLS; and other listed GM-platform vehicles, TX133 supports proper coolant temperature signal delivery for drivability and diagnostic accuracy.

Key Features

• Engine coolant temperature sensor for temperature signal monitoring
• Bolt-on attachment method for service replacement
• 1 female rectangular plug-in connector
• 2 male blade terminals
• Thermistor response values calibrated for measurement accuracy
• 100% factory tested before shipment
• Standard Ignition TX133 part number for catalog and service lookup

Detailed Description

Standard Ignition TX133 is engineered to deliver consistent coolant temperature readings to the engine control system. Accurate coolant temperature data is critical for fuel control, cooling fan operation, and diagnostic trouble code management. This sensor is listed for a broad range of GM vehicles, including Chevrolet Traverse and Malibu, Buick Enclave and LaCrosse, and Cadillac SRX and CTS, making it a practical replacement for common temperature-signal faults.

This part cross-references Bosch 0280130122 and Delphi TS10253 for the same application. The TX133 designation is useful when matching the sensor by part number during repair planning or catalog lookup.

What It Helps Address

• Erratic or inaccurate coolant temperature readings
• Temperature-related check engine light concerns
• Cooling fan control issues tied to sensor input
• Hard starting or poor warm-up behavior caused by incorrect temperature data
• Driveability problems related to faulty engine coolant temperature feedback

Installation Notes and Tips

Verify connector style, terminal count, and mounting style before installation. TX133 uses a female rectangular connector with two male blade terminals and a bolt-on attachment method, so the replacement should be matched to the original sensor configuration. Inspect the connector, wiring, and sealing surfaces during service to help ensure a stable electrical connection.

For fitment verification, confirm the vehicle year, make, and model against the listed applications before ordering. This part is listed for 2000-2017 coverage across multiple GM and related platforms, including Chevrolet Equinox, Pontiac G6, Saturn Aura, and GMC Acadia.

Quality Assurance

Standard Ignition states that it controls the manufacturing process from component selection through finished product assembly. The sensor design uses tight thermistor tolerance targets, and each coolant temperature sensor is factory tested to support consistent operation and dependable service performance.
