Introduction to Coolant Temperature Sensor 6U0919501B 357919501A
The YZHIDIANF engine coolant temperature sensor 6U0919501B is a direct OE replacement for VW Golf, Passat, and Jetta. An NTC thermistor sealed in a corrosion-resistant housing feeds real-time coolant temperature to the ECU for fuel enrichment, ignition timing, and radiator fan control. A failing coolant temperature sensor produces hard cold starts, rich fuel mixtures, and P0115–P0119 fault codes. This plug-and-play unit replaces OE numbers 6U0919501B and 357919501A with no wiring modifications, restoring accurate engine temperature monitoring in under 20 minutes.输入introduction内容

Why Choose Our Coolant Temperature Sensor 6U0919501B 357919501A
Precise Resistance Curve
The NTC thermistor matches the OE resistance-to-temperature curve. At 20°C the ECU gets a reading it can trust. At 90°C operating temperature the signal stays on target. No drift means no unnecessary fuel enrichment.
Sealed Against Contamination
The connector housing uses a rubber gasket to seal out moisture and road grime. Internal contacts are corrosion-resistant. This coolant temperature sensor holds up through years of winter salt, summer heat, and engine bay wash-downs.
Drop-In Installation
The sensor body, O-ring groove, and connector shell match the factory part exactly. Pull the old one, push in the new one, snap the retaining clip. No shaving down plastic tabs or forcing connectors that do not quite fit.
Consistent Batch Quality
Every production batch goes through end-of-line testing against the OE resistance specification at multiple temperature points. Units that fall outside the tolerance band do not ship. What arrives at your door has already passed the same electrical checks we would run on an OE sample.
Works With VW ECU Self-Diagnostics
VW engine management systems run continuous rationality checks on the coolant temperature signal. A sensor that reads implausible values triggers a fault code. This unit outputs a clean signal that passes those checks, so the ECU stays out of limp mode and fuel mapping stays adaptive.
12-Month Replacement Guarantee
If the sensor fails under normal use within 12 months, we replace it. No fine print about installation conditions or diagnostic fees. Send us the order number and a brief description of the issue.
