P0116 2020 Honda CR-V Code - Engine Coolant Temperature Sensor 1 Circuit Range/Performance Problem
Quick Answer
The Powertrain Control Module (PCM) supplies voltage to the engine coolant temperature signal circuit (about 5 V) through a pull-up resistor. Common causes include Faulty Engine Coolant Temperature (ECT) Sensor 1, Engine Coolant Temperature Sensor 1 harness is open or shorted, Engine Coolant Temperature Sensor 1 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.
