P0125 2016 Honda CR-V Code - Engine Coolant Temperature Sensor 1 Malfunction/Slow Response

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 Low engine coolant level, Leaking or stuck open thermostat, Faulty Engine Coolant Temperature (ECT) Sensor 1. 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.

Code P0125 2016 Honda CR-V Description

The Powertrain Control Module (PCM) supplies voltage to the engine coolant temperature signal circuit (about 5 V) through a pull-up resistor. As the engine coolant cools, the Engine Coolant Temperature (ECT) Sensor 1 resistance increases and the PCM detects a high signal voltage. As the engine coolant warms, the ECT Sensor 1 resistance decreases, and the PCM detects a low signal voltage. If the ECT Sensor 1 output voltage does not reach a specified temperature at which closed-loop control for stoichiometric air/fuel ratio starts within a set time, depending on the initial engine coolant temperature after starting the engine, the PCM detects a malfunction and stores a Diagnostic Trouble Code (DTC).
