In this video, you will find the exact location of the Cylinder Head Temperature (CHT) Sensor. If you are troubleshooting an overheating issue, clearing a dashboard warning light, or preparing to replace this critical engine sensor, knowing its precise position beforehand will save you a lot of time and effort.
How this video helps you: Unlike regular coolant sensors, the CHT sensor is usually tucked directly into the metal casting of the cylinder head, often hidden completely underneath deep engine components, wiring harnesses, or intake manifolds. This quick and clear visual guide shows you exactly where the sensor is situated on the engine block. You can see its position perfectly, find it on your own vehicle in seconds, and know exactly what you are dealing with before starting your project.
Common symptoms of a bad Cylinder Head Temperature (CHT) Sensor: The CHT sensor measures the actual metal temperature of the engine cylinder head. When it fails or sends a faulty signal, it can cause severe engine management and safety issues, including:
- Check Engine Light (CEL): The computer will quickly flag a circuit or temperature reading error, throwing codes such as P1289 or P1290.
- False Overheating Gauge Readings: Your dashboard temperature gauge may suddenly spike to hot or drop to dead cold erratically, even if the engine is running normally.
- Engine Enters “Fail-Safe” or Limp Mode: To prevent engine melting, a bad sensor signal can trick the computer into shutting down cylinders, dropping power significantly, and limiting your speed.
- Radiator Cooling Fans Running Constantly: The vehicle’s computer may run the cooling fans at maximum speed non-stop as a safety precaution due to missing temperature data.
- Hard Starting or Rough Idling: Incorrect temperature readings disrupt the fuel-to-air mixture calibration, causing the engine to struggle when starting up cold.
