Detailed Description

Global Parts 1814523 is built to provide the ECM with accurate coolant temperature readings, which are critical for fuel control, cooling fan operation, and overall engine temperature management. When the sensor signal becomes inaccurate, the vehicle can experience cooling system concerns and overheating-related drivability issues. This replacement sensor is made to OE specifications and uses a blade terminal layout with one oblong female connector and two male terminals for the listed applications. This part cross-references Standard Ignition TX279 and TX307 for the same application.

What It Helps Solve

  • Incorrect coolant temperature readings at the ECM
  • Cooling fan operation problems tied to sensor input
  • Overheating concerns caused by a failing temperature sensor
  • Engine management issues related to inaccurate coolant data
  • Check engine concerns associated with coolant temperature signal faults

Installation Notes and Tips

Verify connector shape, terminal count, and terminal gender before installation. Confirm the sensor location on the engine cooling circuit and compare the original connector to the oblong female plug and blade terminals on Global Parts 1814523. After installation, clear any stored fault codes and confirm the ECM is reading coolant temperature correctly on the applicable Toyota Yaris, Toyota Yaris iA, or Scion iA.

Quality Assurance

Global Parts coolant temperature sensors are engineered as direct OE-style replacements and are built to meet OE specifications for the listed vehicles. Part number 1814523 is intended to restore accurate coolant temperature reporting for the specified fitments.
