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.
