Temperature Sensor Cyl Head.
Maintain accurate engine management with this OE Match Cylinder Head Temperature Sensor, manufactured as a direct replacement. Produced to OE-style specifications, this sensor is designed to monitor cylinder head temperature and provide the engine management system with precise temperature data, allowing it to adjust fuel delivery and ignition timing for optimum engine performance, efficiency, and drivability.

Fits:
  • Porsche 914 (1970-1976)

Over time, temperature sensors can deteriorate through repeated heat cycles, vibration, and age, leading to inaccurate temperature readings or complete sensor failure. A faulty cylinder head temperature sensor can cause poor starting, rough running, increased fuel consumption, and incorrect fuel mixture adjustments. Replacing the sensor restores accurate engine temperature monitoring and helps ensure the engine management system performs as intended. This OE Match cylinder head temperature sensor is ideal for routine maintenance, engine repairs, and Porsche restoration projects.  

What This Product Does:
  • Monitors the temperature of the engine cylinder head.
  • Sends accurate temperature data to the engine management system.
  • Helps optimise fuel delivery and ignition timing.
  • Supports efficient engine performance and fuel economy.
  • Contributes to reliable cold starting and smooth engine operation.
  • Replaces faulty or inaccurate original temperature sensors.
  • Provides an OE-style fit and dependable quality.

Symptoms Of Wear Or Failure:
  • Difficult cold or hot starting.
  • Rough idle or uneven engine running.
  • Increased fuel consumption.
  • Poor engine performance.
  • Engine hesitation during acceleration.
  • Incorrect fuel mixture caused by inaccurate temperature readings.
  • Faulty sensor identified during engine diagnostics or restoration work.

Why Replacement Matters:

  • The cylinder head temperature sensor is a critical engine management component that provides the control unit with accurate information about engine operating temperature. This data allows the engine management system to make precise adjustments to fuel injection and ignition timing, ensuring efficient combustion, reliable starting, and smooth engine performance.
  • A faulty sensor can send inaccurate temperature readings, resulting in incorrect fuel mixtures, poor drivability, increased fuel consumption, and unnecessary strain on the engine. Replacing a worn or failed sensor restores accurate temperature monitoring and helps maintain reliable engine operation. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Cylinder Head Temperature Sensor provides the correct fit, dependable performance, and long-lasting durability, making it an excellent choice for Porsche maintenance, repairs, and restoration projects.

About Temperature Sensor

Temperature Sensors – Accurate Engine Monitoring for Porsche Performance

Temperature sensors play a critical role in your Porsche’s engine and cooling system by constantly monitoring temperatures such as coolant, oil, intake air, and exhaust gases. These sensors send real-time data to the engine control unit (ECU), helping to regulate performance, emissions, and fuel efficiency.

At Design911, we stock a comprehensive selection of genuine and high-quality temperature sensors for various Porsche models such as 911, Boxster, Cayman, Cayenne, Macan, and Panamera models. Each sensor is designed for precision, reliability, and longevity — ensuring accurate readings and smooth engine operation in all driving conditions.

What Do Temperature Sensors Do?

Temperature sensors are vital to maintaining your Porsche’s performance, safety, and efficiency. Their main functions include:

  • Monitoring coolant and engine temperature to prevent overheating.
  • Feeding data to the ECU to adjust fuel mixture and ignition timing.
  • Controlling fan activation and emission systems.
  • Ensuring optimal engine performance under all loads and climates.

Accurate sensor readings are essential for protecting your engine, maximising power, and improving fuel economy.

Why Do Temperature Sensors Fail?

Constant exposure to heat, vibration, and contaminants can cause temperature sensors to degrade or fail. Common causes include:

  • Thermal fatigue leading to inaccurate readings.
  • Corrosion or oxidation on connectors.
  • Coolant or oil contamination damaging sensor elements.
  • Wiring faults or loose electrical connections.
  • Age-related wear causing signal irregularities.

Symptoms of a failing temperature sensor include fluctuating temperature gauge readings, poor fuel economy, rough idle, overheating, or an illuminated check engine light.

Why Replace Faulty Temperature Sensors?

Replacing a faulty temperature sensor is essential for accurate engine management and protection. A malfunctioning sensor can cause incorrect fueling, overheating, and even engine damage.

Benefits of replacement include:

  • Accurate temperature readings and ECU adjustments.
  • Enhanced fuel efficiency and performance.
  • Prevention of overheating and engine damage.
  • Reliable operation with manufacturer-quality precision.

All sensors in our range are made using high-grade materials and advanced sensing elements to provide reliable data, quick response times, and long service life in even the most demanding conditions.
