What does cylinder head over temperature protection active mean?
What does cylinder head over temperature protection active mean?
Error Code P1299 is defined as Cylinder Head Temperature Sensor Detected Engine Overheating Condition. This means there’s an overheat condition, which is caused by multiple factors, such as a faulty thermostat, and low engine coolant.
Note that the definition “Cylinder Head Over-temperature Protection Active” refers to both the facts that an overheating condition exists, and that the PCM has initiated a “Fail Safe” mode, which is a series of actions designed to prevent the engine from overheating further to help protect it against suffering potentially fatal damage.
What does the p1299 cylinder head temperature sensor detect?
Indicates an engine overheat condition was detected by the Cylinder Head Temperature (CHT) sensor. A Failure Mode Effects Management (FMEM) strategy called fail-safe cooling was activated to cool the engine. Need more information on how to fix the P1299 FORD code? Need more help?
How much does a cylinder head temperature sensor cost?
Most auto repair shops charge between $75 and $150 per hour. The Cylinder Head Temperature (CHT) Sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as temperature increases, and the resistance increases as the temperature decreases.
How does the resistance of a cylinder head change with temperature?
The Cylinder Head Temperature (CHT) Sensor is a thermistor device in which resistance changes with temperature. The electrical resistance of a thermistor decreases as temperature increases, and the resistance increases as the temperature decreases.

What is DTC for cylinder head temperature sensor?
Using both the CHT sensor and fail-safe cooling strategy, the PCM prevents damage by allowing air cooling of the engine and limp home capability. The Diagnostic Trouble Code (DTC) indicates an engine overheat condition was detected by the Cylinder Head Temperature Sensor.
How does CHT work on a cylinder head?
In terms of operation, the CHT sensor converts the temperature of the cylinder head into a signal voltage (or resistance) that changes as the temperature changes.
What are the symptoms of a bad cylinder head temperature sensor?
One of the first symptoms commonly associated with a bad or failing cylinder head temperature sensor is a a long cranking time. The signal provided by the cylinder head temperature sensor monitors an important parameter, and problems with it can cause all sorts of issues, one of them being an extended cranking time when starting the vehicle.
How to check the p1299 Ford cylinder head temperature sensor?
Start by checking the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. What does this mean? The cost to diagnose the P1299 FORD code is 1.0 hour of labor.
What to do if your cylinder head overheats?
Monitor the temperature gauge carefully. If you have determined the cause of the overheat is the faulty cylinder head temperature sensor, then have that sensor replaced. Repair or replace open or shorted cylinder head temperature sensor. Repair or replace electrical connection in the cylinder head temperature sensor.

What does it mean when cylinder head temperature sensor is detected?
Indicates an engine overheat condition was detected by the Cylinder Head Temperature (CHT) sensor. A Failure Mode Effects Management (FMEM) strategy called fail-safe cooling was activated to cool the engine. Need more information on how to fix the P1299 FORD code?
What causes a temperature sensor to go off on a Ford p1299?
P1299 FORD Possible Causes. Low engine coolant. Faulty Thermostat. Faulty Cylinder Head Temperature Sensor. Cylinder Head Temperature Sensor harness is open or shorted. Cylinder Head Temperature Sensor circuit poor electrical connection.
