BRAND NEW *OEM Quality* coolant temperature sensor to suit VW Golf / Bora / Passat B5 / New Beetle / Transporter T5 / Vento.

If your VW is throwing a P0115-P0119 fault code, running rich when warm, showing an inaccurate temperature gauge, or struggling with cold starts, a failed coolant temperature sensor is one of the most likely causes. This direct OEM replacement fits the standard 4-pin square green connector - dispatched same-day before 12pm from Cranbourne VIC.

PACKAGE INCLUDES

1 x BRAND NEW coolant temperature sensor (4-pin square green connector). Includes seal and retaining ring. Direct OEM replacement - no wiring modification required.

ABOUT THIS SENSOR

The coolant temperature sensor monitors engine coolant temperature and sends a signal to the ECU. The ECU uses this data to adjust fuel injection timing, fuel mixture, idle speed, and ignition timing - especially critical during cold starts and warm-up.

This sensor uses an NTC (Negative Temperature Coefficient) thermistor - resistance drops as temperature rises. A failed sensor sends an incorrect signal to the ECU, causing the engine to behave as if it is permanently cold or hot. This is a direct plug-in replacement with the OEM 4-pin square green connector.

COMMON SYMPTOMS OF FAILURE

Check Engine light with codes P0115 P0116 P0117 P0118 P0119
Engine running rich when warm - black smoke or strong fuel smell
Poor cold-start performance or extended warm-up time
Inaccurate or erratic temperature gauge reading
Increased fuel consumption
Rough idle or hesitation at operating temperature

How do I test a coolant temperature sensor?

The most common test is to measure the sensor resistance with a multimeter at a known coolant temperature and compare against the manufacturer resistance curve. A cold engine (20 degrees C) typically reads 2,000 to 3,000 ohms and drops to around 200 to 300 ohms at operating temperature (90 degrees C). An OBD2 scanner showing a fixed temperature reading that does not change as the engine warms up is also a strong indicator of sensor failure.

Can a faulty coolant temperature sensor cause my engine to overheat?

Indirectly yes. If the sensor reports a lower temperature than actual, the ECU may not activate the cooling fan at the correct time, allowing the engine to overheat. It can also suppress the dashboard warning light, meaning you may not be alerted until the engine is already at a dangerously high temperature. Replace a suspected faulty sensor promptly.

Do I need to drain the coolant to replace the sensor?

Not always - many coolant temperature sensors can be replaced quickly with minimal coolant loss if you work fast and have a replacement ready to thread in immediately. However on some vehicles the sensor location requires partial coolant drainage. Check the sensor position on your specific engine before starting. Always use fresh coolant when topping up after replacement.

What are the symptoms of a faulty coolant temperature sensor?

Symptoms include poor fuel economy, black smoke, engine overheating warning, incorrect temperature gauge reading, hard starting when cold, and rough idle. Fault codes P0115 to P0119 are commonly associated with coolant temperature sensor faults.

Is it safe to drive with a bad coolant temperature sensor?

A faulty coolant temperature sensor can cause the ECU to run rich fuel mixtures and prevent the cooling fan from operating correctly, risking engine overheating. Replace it promptly - it is a low-cost part that can prevent expensive engine damage.

How do I know if my coolant temperature sensor or my thermostat is faulty?

A faulty thermostat typically causes the engine to overheat or never reach operating temperature. A faulty coolant temp sensor causes incorrect gauge readings and running issues but the coolant itself may be at the correct temperature. An OBD2 scanner showing live coolant temp data helps distinguish between the two.

Are there two coolant temperature sensors on my vehicle?

Many vehicles have two sensors - one for the ECU (engine management) and one for the dashboard temperature gauge. They look similar but are not interchangeable. Check your vehicle's service manual or contact us with your vehicle details to confirm which sensor you need.
