Genuine Bentley Coolant Temperature Sensor 06A919501A

Restore the accuracy of your engine management system with this Genuine Bentley Coolant Temperature Sensor. Part number 06A919501A is the updated "Green" 4-pin design, engineered to replace the older, less reliable black or blue versions found in earlier models.

Technical Specifications & Fitment:

• Part Number: 06A919501A (Includes O-Ring)

• Connector Type: 4-Pin Oval Plug (Green Housing)

• Compatibility: Bentley Continental GT, GTC, Flying Spur (2003–2018), Mulsanne (2011–2020), and late Arnage models.

• Function: Dual-circuit sensor providing data to both the Engine Control Unit (ECU) and the Instrument Cluster.

Why Genuine Bentley Sensors Matter: Aftermarket temperature sensors are notorious for having the wrong resistance curves, leading to "Check Engine" lights (P0117/P0118) or cooling fans running at high speed constantly. This Genuine unit ensures your W12 or V8 engine operates at the correct stoichiometric ratio by reporting exact temperature data, which is vital for cold-start performance and emissions compliance.

Technical Integration Tip

When installing the Genuine 06A919501A Temp Sensor, only perform the replacement when the engine is completely cold. The sensor is held in place by a plastic "C-clip" (Part No. 032121142); these clips become brittle over time, so we highly recommend having a spare on hand as they often snap during removal. Always ensure the old O-ring is removed from the housing before inserting the new sensor; if the old ring stays inside, the new sensor will not seat correctly, leading to a high-pressure coolant spray once the system reaches operating temperature. After installation, use a diagnostic tool to clear any stored "Coolant Circuit" fault codes to reset the radiator fan duty cycle.
