Air Charge Temperature Sensor for Porsche and Saab
Facet 10.4003 is an air charge temperature sensor for select Porsche and Saab applications. It provides the intake air temperature signal used by the engine management system to help maintain accurate fuel and ignition control.
Key Features
- Air charge temperature sensor for engine management systems
- Direct fit for select Porsche 911, Saab 900, and Saab 9000 applications
- Supports intake air temperature monitoring for proper ECU input
- Facet 10.4003 replacement part number for service and repair
Detailed Description
Facet 10.4003 is an engine sensor used to measure the temperature of incoming air before it reaches the combustion chamber. On vehicles such as the 1994-1998 Porsche 911, 1994-1995 Saab 900, and 1995 Saab 9000, this signal helps the engine control unit adjust operating parameters based on air density and temperature. If the original sensor is inaccurate or failing, replacing it with the correct air charge temperature sensor can restore proper sensor input for the engine management system.
This part number, 10.4003, is a practical choice for owners and technicians servicing Porsche 911 and Saab turbo or fuel-injected applications that rely on accurate intake air temperature data.
What It Helps Address
- Incorrect intake air temperature readings
- Rough idle caused by faulty sensor input
- Hard starting related to poor engine data
- Fuel mixture issues from inaccurate air temperature signals
- Check engine light conditions tied to sensor faults
Installation Notes and Tips
Verify connector style, sensor location, and OE part match before installation. Clear diagnostic trouble codes after replacement and confirm the engine management system reads intake air temperature correctly. For fitment, this part fits 1994-1998 Porsche 911, N/A; fits 1994-1995 Saab 900, N/A; and fits 1995 Saab 9000, N/A.
Quality Assurance
Facet manufactures engine management components for service replacement use. Part number 10.4003 is built for the listed applications and should be matched to the vehicle’s original sensor specification before installation.
