What It Helps Address

• Incorrect coolant temperature readings
• Hard starting or rough idle related to temperature signal errors
• Cooling fan control concerns caused by inaccurate sensor input
• Fuel mixture issues tied to coolant temperature data
• Check engine light conditions related to coolant temperature sensor faults

Installation Notes and Tips

Verify connector shape, terminal count, and attachment style before installation. Confirm the vehicle application against the listed fitment, especially for 1999 Volkswagen Jetta models, which are not compatible with distributor-equipped vehicles. Inspect the connector and wiring for corrosion, looseness, or heat damage before installing the new sensor. Match the original sensor configuration to the vehicle’s cooling system and engine management setup.

Quality Assurance

Standard Ignition supplies replacement electrical and engine management components for service applications. TS-377 is built to match the listed connector and terminal configuration for the specified Volkswagen fitments.
