U210A Mercury Code - Temperature Sensor Circuit Voltage
Quick Answer
The Diagnostic Trouble Code (DTC) will set in continuous memory in the Head-Up Display (HUD) Module when the internal Temperature Sensor circuit is below the lowest or above the highest valid temperature value. Common causes include Faulty Temperature Sensor, Temperature Sensor harness is open or shorted, Temperature Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
