Detailed Description

The Standard Ignition TX87 coolant temperature sensor is designed to deliver reliable temperature feedback to the engine management system. Accurate coolant temperature data is critical for fuel control, idle quality, cooling fan operation, and overall drivability. Standard Ignition manufactures this sensor with controlled component-to-finished-product production and tests each unit at the factory to help ensure dependable performance. The TX87 also benefits from broad sensor coverage, making it a practical replacement for service work on vehicles such as the Ford Ranger, Ford Explorer, and Mercury Mountaineer. This part cross-references Bosch 12046 and Beck/Arnley 158-0782 for the same application.

What It Helps Fix

• Incorrect coolant temperature readings on the dash or scan tool
• Hard starting or rough cold operation caused by faulty temperature input
• Cooling fan control issues tied to inaccurate sensor data
• Rich or lean fuel mixture concerns related to engine temperature reporting
• Check engine light conditions associated with coolant temperature sensor faults
