Key benefits Restores accurate cabin temperature readings so your HVAC system can heat and cool more efficiently. Directfit replacement for Tesla Model 3 (2021–2023) and Model Y (2021–2023) with OE number 110681800A — no modification required. Durable ABS housing in black resists moisture and environmental wear, while maintaining consistent thermal sensitivity for reliable performance. Plugandplay installation: inserts into the existing port with no special tools or complex calibration. What this part does Function: cabin air temperature sensor for the vehicle HVAC/climate control system. It measures cabin air temperature and provides precise signals for automatic climate regulation. Compatibility: designed specifically as a direct replacement for Model 3 2021–2023 and Model Y 2021–2023 (OE 110681800A). Fit and form: matches OEM form factor and connection so it seats correctly in the factory port and communicates with the vehicle's control system. Material and performance Housing: ABS plastic in black for longlasting durability under varying temperature and humidity. Performance: tested with advanced diagnostic equipment to verify accurate signal transmission and consistent thermal response. Resistance: engineered to resist moisture erosion and maintain sensitivity over time. What's included 1 × air temperature sensor (replacement unit only). Quick installation by inserting into the existing sensor port; no additional tools required. Use scenarios a failed or intermittent cabin temperature sensor that is causing uneven heating or cooling, or triggering HVAC fault codes. Swap in a sensor after water intrusion or interior cleaning that may have damaged the original sensor's housing or connector. Install as part of a routine HVAC restoration when restoring climate accuracy after repairs to the dash, blower, or control module. Installation notes Designed for quick, tool replacement in the factory sensor location. Ensure the connector is fully seated and secure. No special calibration is required in most cases; the sensor is plugandplay with the vehicle's existing HVAC control system. If diagnostic trouble codes remain, follow vehicle manufacturer diagnostic procedures. Trust and compatibility Direct replacement for the specified Tesla models with OE number 110681800A. Tested for signal accuracy and built to match the OEM fit and function for reliable climate control operation.
