![]() Failed emissions test or monitors “not ready” for emissions testing.A P0128 will usually not be as noticeable due to a reduced fuel economy.The temperature gauge indicates cooler than it usually does.Driving on the highway causes the temperature of your engine to drop significantly.These are the most common symptoms you will experience if your car is triggering the P0128 code. The engine computer (PCM) software must be updated.Faulty engine coolant temperature (ECT) sensor.Coolant bypassing closed thermostats because the thermostat seal isn’t sealing properly.Code P0128 will be triggered if either of these faults is again recorded on the next engine start.Īlso Read: P0456 Code – Meaning, Causes, Symptoms & Fixes What Causes The P0128 Code? If any one of these criteria is not met, the PCM will report it to the PCM. The engine temperature recorded must not drop below 160 F after the threshold of 160 F has been reached. The powertrain control module commands the fuel system to enter “closed-loop,” where oxygen sensor readings are used to maintain a 14.7:1 ratio.ĮCMs require that the Engine coolant temperature sensor records temperatures beyond 160 F within 15 minutes after the engine starts. The engine control module (ECM), which tracks the time it takes for a vehicle’s engine to reach the operating temperature, monitors this temperature. The P0128 code indicates that the engine coolant is not getting heated up fast enough, which means that the engine’s operating temperature is not reaching a specified temperature within a given time.
