• Hard starting or rough idle caused by inaccurate temperature input
• Cooling fan operation issues tied to sensor signal problems
• Fuel mixture concerns from faulty engine temperature data

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. The TX143 uses a bolt-on attachment method and a single rectangular female connector, so matching the OE connector and sensor location is important. For the 2014 Cadillac XTS application, confirm the radiator-mounted engine coolant temperature sensor position before ordering. Always inspect the connector, wiring, and sealing surfaces for corrosion or damage during replacement.
