This Sensor Sends The Temperature Readings To The Climatronic Unit To Keep Your Heating And A/C Systems Operating Properly. If The Sensor Gives Incorrect Readings, The Climatronic System May Not Function Properly And The Air Temperature That Is Blown Out Through The Vents May Not Correlate With The Current Setting. Keep Your Climatronic System Working Correctly With A New Temperature Switch.
This Switch Is Located On The Lower Center Position Of The Evaporator Housing And Relays The Temperature Of The Air After The Heater Core/Evaporator.

Porsche Temperature Sensors & Switches - Accurate Climate & System Control
Porsche temperature sensors and switches play a vital role in monitoring and regulating heating, air conditioning, and engine-related temperature systems. By continuously measuring temperature and sending accurate data to control units, these components ensure efficient cabin climate control, system protection, and reliable vehicle operation.
Available from Design911, temperature sensors and switches are supplied to OEM standards, making them ideal for maintenance, fault repair, and restoring proper HVAC system performance.
What Do Porsche Temperature Sensors & Switches Do?
Temperature sensors and switches provide real-time temperature data and system protection.
Core Functions:
- Monitor cabin, evaporator, and coolant temperatures
- Regulate heating and air conditioning output
- Trigger cooling fans or system protection responses
- Prevent system overheating or freezing
- Ensure consistent passenger comfort
Accurate sensor readings are essential for efficient climate control and system longevity.
Why Do Temperature Sensors & Switches Fail?
Temperature sensors operate in environments exposed to heat, moisture, and electrical load.
Common Causes of Failure:
- Sensor degradation due to age and heat cycling
- Electrical faults or wiring corrosion
- Moisture ingress affecting sensor accuracy
- Internal switch wear or sticking
- Contamination from dust or debris
Failure can lead to incorrect temperature readings, poor climate performance, or warning lights.
When Should Temperature Sensors & Switches Be Replaced?
Porsche temperature sensors and switches should be inspected
and replaced if the following symptoms occur:
- Inconsistent or incorrect cabin temperature
- HVAC system not responding correctly
- Air conditioning cutting out or overcooling
- Fault codes related to temperature regulation
- During HVAC system servicing or repairs
Timely replacement restores accurate system control and passenger comfort.
Highlights
- Essential Porsche HVAC monitoring components
- Ensures accurate temperature regulation
- Supports efficient heating and air conditioning
- OEM-spec reliability and fitment
- Suitable for diagnostics, repairs, and maintenance
