Diagram Ref No 35

Coolant temperature is an important parameter for both engine performance and cooling-system management. As the engine warms from a cold start to normal operating temperature, the sensor continuously provides temperature information that can be used by the ECU for temperature-dependent operating strategies.

The sensor operates in a demanding environment, exposed to hot coolant, pressure and repeated heating and cooling cycles. Over time, the sensing element or electrical connections can deteriorate, causing inaccurate, intermittent or implausible temperature readings.

A defective sensor may incorrectly report that the coolant is hotter or colder than it actually is. This can result in warning messages, diagnostic fault codes and incorrect engine-management behaviour.

This OE Match Water Temperature Coolant Sensor provides a high-quality replacement for a failed or inaccurate original sensor.

What This Product Does:

• Measures engine coolant temperature.
• Provides temperature information to the relevant electronic control system.
• Helps determine whether the engine is cold, warming up or at operating temperature.
• Supports temperature-dependent engine-management strategies.
• Helps maintain correct warm-up operation.
• Supports accurate monitoring of cooling-system temperature.
• Can contribute to cooling-fan control depending on vehicle specification.
• Helps identify abnormal coolant temperatures.
• Supports engine protection and diagnostic functions.
• Helps maintain consistent engine operation as temperature changes.
• Replaces a faulty, inaccurate or intermittent temperature sensor.
• Provides an OE Match replacement for compatible Porsche applications.  

Symptoms Of Wear Or Failure:

• Check engine or engine-management warning light.
• Cooling-system warning messages.
• Coolant temperature-related diagnostic fault codes.
• Incorrect coolant temperature readings.
• Temperature readings that are unusually high or low.
• Temperature values changing suddenly or erratically.
• Difficult cold starting. Rough running during warm-up.
• Unstable idle. Increased fuel consumption.
• Poor engine performance while warming up.
• Cooling fans operating unexpectedly.
• Cooling fans running excessively.
• Cooling-fan behaviour inconsistent with actual engine temperature.
• Intermittent temperature information.
• Damaged or corroded electrical connector.
• Damaged wiring near the sensor.
• Coolant leakage around the sensor or its seal.  

Why Replacement Matters:

• Accurate coolant-temperature information allows the vehicle's electronic systems to respond correctly as engine temperature changes.
• When the engine is cold, its operating requirements differ from those at normal working temperature. If a defective sensor reports an incorrect temperature, the ECU may make adjustments based on inaccurate information.
• For example, a sensor incorrectly indicating a cold engine can potentially cause inappropriate warm-up strategies to remain active. This may contribute to poor running, increased fuel consumption or higher emissions.
• An incorrectly high reading can cause different control responses and may also make genuine cooling-system faults more difficult to diagnose.
• Intermittent sensors can be particularly problematic because they may operate normally at certain temperatures before suddenly producing implausible values. This can lead to intermittent warning lights, fault codes or inconsistent engine behaviour.
• Replacing a confirmed faulty sensor with this OE Match Water Temperature Coolant Sensor helps restore reliable temperature feedback and correct temperature-dependent system operation.
