2021年7月21日 · What are the common symptoms of an OBDII code P0128 (Coolant Thermostat Malfunction)? - The common symptoms include the engine running hotter or colder than normal, decreased fuel efficiency, and the Check Engine light illuminating.

When your check engine light is illuminated due to trouble code P0128, you may have an issue with your engine thermostat. Here are some helpful steps to take to find out how do I fix trouble code P0128? Learn how to solve this trouble code and repair your thermostat.

The P0128 code indicates that your powertrain control module (PCM) monitors that the coolant temperature is lower than the thermostat regulating temperature. For your engine to work efficiently, it’s essential that the engine reaches its designated normal operating temperature.

2021年7月31日 · The code P0128 - Coolant Temperature Below Thermostat Regulating Temperature means that the engine does not reach expected temperature after running for sufficient time, or in other words, it takes too long to warm up. Often this code causes the Check Engine light to come on and off in cold temperatures.

Low coolant levels, a stuck engine coolant thermostat, and issues with the coolant temperature sensor or its wiring can cause code P0128. Symptoms of the P0128 code include an illuminated check engine light, longer warm-ups, and significantly decreased engine temperatures while driving on a highway.

Past experience indicates that the most likely solution for a P0128 is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code: Verify coolant strength & level; Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
