What This Product Does
This sensor measures intake-air temperature, providing an input used by the engine control system when determining fuelling adjustments. It monitors incoming air rather than coolant temperature, so coolant-gauge or radiator-fan faults should not automatically be attributed to this component.
Functions
- Measures temperature within the intake system.
- Provides temperature information to engine management.
- Supports temperature-dependent fuelling calculations.
Technical Details
- Part reference: 99660611300; brand: OE Match.
Symptoms of Fault
- Implausible or intermittent intake-temperature readings in diagnostic data.
- Engine-management warning or a temperature-signal fault code.
- Rough running, difficult starting or increased fuel consumption where incorrect temperature information affects fuelling.
Why Replacement Matters
A confirmed sensor fault can leave engine management working with incorrect temperature information. Replacing the defective component addresses that input, but connector corrosion, damaged terminals and wiring faults should be investigated first because they can produce similar symptoms.
FAQs
Does a fault code prove the sensor needs replacement?
No. Use the code alongside live readings and electrical checks before deciding which component is responsible.
What should be inspected first?
Check the connector, terminals and nearby wiring for damage or corrosion, then test the signal using the appropriate vehicle-specific procedure.
Can similar-looking sensors be interchanged?
Appearance alone does not establish compatibility. Match reference 99660611300 and the relevant model, engine and production-year details.

The OE MATCH Porsche Fuel Temperature Sensor is a engine management component designed to accurately monitor the temperature of the fuel within the fuel system on compatible Porsche models. This precision-engineered sensor continuously measures fuel temperature and transmits real-time data to the engine control unit (ECU), allowing the fuel injection system to optimise fuel delivery, combustion efficiency and emissions performance.

The sensor is engineered to withstand continuous exposure to fuel, pressure fluctuations, vibration and varying operating temperatures. Designed as a replacement, it integrates seamlessly with the vehicle's engine management system, delivering correct performance and long-term reliability.
What This Product Does:
- Continuously monitors the temperature of the fuel.
- Sends accurate temperature data to the engine control unit (ECU).
- Allows the ECU to optimise fuel injection and combustion.
- Supports efficient engine performance and fuel economy.
- Helps reduce exhaust emissions.
- Assists reliable cold and hot engine operation.
- Forms an essential part of the engine management and fuel injection system.
Symptoms Of Wear Or Failure:
- Illuminated engine management or check engine warning light.
- Engine management fault codes relating to the fuel temperature sensor.
- Poor engine performance.
- Rough idle.
- Hesitation during acceleration.
- Increased fuel consumption.
- Difficult hot or cold starting.
- Reduced engine efficiency.
- Increased exhaust emissions.
- Intermittent engine management issues.
Why Replacement Matters:
- The fuel temperature sensor operates continuously in a demanding environment, where it is exposed to fuel, pressure changes, engine heat and constant vibration. Over time, the sensing element or internal electronics can deteriorate, causing inaccurate temperature readings or complete sensor failure.
- A faulty fuel temperature sensor can provide incorrect data to the ECU, leading to improper fuel injection calculations, reduced engine performance, poor fuel economy and increased emissions. If left unresolved, it may also trigger engine management warning lights and affect the overall efficiency of the fuel injection system.
