This is one of the most frequent OBD2 trouble codes. Read the full article below to know what it means, how to fix it, and what other codes may show related to it. Like the thermostat in your home tells you how hot or cold it is inside, the thermostat in your vehicle tells your vehicle ECM Electronic Control Module the current temperature of your engine. Your ECM uses that input to adjust engine coolant flow and keep your engine at optimal operating temperature. The name for this entire system of sensors and electronic components is called the thermostat heater control circuit THCC. When that happens, your vehicle will code a P and your Check Engine Light will illuminate. Verifying the symptoms of a P code can be tricky. Depending on the position of the thermostat at the time of malfunction, you may not even notice any problems with your engine until it starts overheating. You are more likely to see an illuminated Check Engine lamp first, or you may get an engine overheating temperature warning in cool weather. Additionally, you may observe your engine cannot reach optimal temperature quickly in warm weather.
