Code P1299 2000 Ford F150 Description
The CHT sensor is installed in the aluminum cylinder head and measures the metal temperature. The CHT sensor can provide complete engine temperature information and can be used to infer coolant temperature. If the CHT sensor conveys an overheating condition to the PCM, the PCM initiates a fail-safe cooling strategy based on information from the CHT sensor. A cooling system concern such as low coolant or coolant loss could cause an overheating condition. As a result, damage to major engine components could occur. 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. A Failure Mode Effects Management (FMEM) strategy called fail-safe cooling was activated to cool the engine.
What are the Possible Causes of the DTC P1299 2000 Ford F150?
- Low engine coolant
- Faulty Thermostat
- Faulty Cylinder Head Temperature (CHT) Sensor
- Cylinder Head Temperature Sensor harness is open or shorted
- Cylinder Head Temperature Sensor circuit poor electrical connection
How to Fix the DTC P1299 2000 Ford F150?
