P1299 FORD, LINCOLN, MAZDA, MERCURY: CYLINDER HEAD TEMPERATURE SENSOR DETECTED ENGINE OVERHEATING CONDITION
The cylinder head temperature sensor (CHT) is an electronic device that is part of the engine management system, and its function is to measure the temperature of the engine’s cylinder head. The temperature is a very important factor involved in the engine’s performance and is one of the parameters used by the ECM (Engine Control Module) to determine the time and fuel needed to achieve greater engine performance. This sensor is essential in engine management, taking into account that the readings it provides are critical for engineering calculations.
Fault code P1299 OBDII is set because the cylinder head temperature sensor detected an overheating condition, which is caused by multiple factors.
It is important to note that if you find that the temperature gauge is set to red, you should stop the engine as soon as possible to allow it to cool down and avoid further damage.
The reasons for setting the diagnostic code P1299 OBD2 are
The steps to solve the DTC code P1299 OBDII are the following:
