Product Overview
The temperature sensor reports engine/coolant temperature to the vehicle’s control or warning system. An inaccurate or failed sensor can contribute to incorrect temperature readings, cooling-fan control issues or fault codes depending on the specific Ranger electrical system.
Matching catalogs cross-reference 4010644 with sensor numbers such as 0281002209 and 0280130093/094. Polaris model-year and engine differences matter, so connector shape and the original sensor number should be matched before ordering.
Key Features & Performance
- Coolant/engine temperature sensing for compatible Ranger applications
- Reference 4010644
- Cross-referenced Bosch-style sensor numbers in matching catalogs
- Useful repair for confirmed sensor signal faults or physical sensor failure
