Where is the cylinder head temperature sensor?
The Ford Transit cylinder head temperature sensor, or CHT, is used in the same way an engine coolant temperature sensor is. Located next to the cylinder head toward the back of the engine block, it monitors the temp of the head and sends this data to the van’s main computer.
What does the head temperature sensor?
Thermometrics Cylinder Head Temperature Sensor is designed to take the place of one of the cylinder head bolts on a diesel engine. The sensor’s purpose is to measure the cylinder head temperature and to signal the vehicle’s operator if an engine overheats (that is, if an engine over-temperature is taking place).
How do you replace a temperature sensor?
- With the engine and coolant entirely cooled down, disconnect the battery.
- Remove any plastic engine covers.
- Locate the coolant temp sensor.
- Partially drain the cooling system, or perform a coolant flush, if it is due.
- Disconnect the electrical connector from the sensor by pushing on the tab and pulling the connector.
Can a car run without a coolant temperature sensor?
Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently, but a DTC (Diagnostic Trouble Code) will be logged in the PCM.
Is the cylinder head temperature sensor the same as the coolant temperature sensor?
Temperature is one of the most important engine parameters that the computer uses to calculate timing and fuel for maximum engine performance and efficiency. The cylinder head is similar in purpose to the coolant temperature sensor, however, it is more accurate due to the construction and operation of the sensor.
What is the advantage of a cylinder head temperature sensor over an engine coolant temperature sensor?
One benefit of the CHT sensor is it takes its readings directly from the metal of the engine as opposed to other models such as the engine coolant temperature (ECT) sensor, which bases its reading on the temperature of the coolant it’s submerged in.
How does a temperature sensor work on a Ford?
As the temperature increases the resistance decreases causing a voltage drop to occur on the 5 volts signal wire. The PCM receives the various voltage signals and equates it to a temperature value. All sounds like a pretty standard sensor. That is until you actually use Ford’s material to diagnose sensor fault issues.
What is a CHT sensor on a Ford?
That is until you actually use Ford’s material to diagnose sensor fault issues. There you will find the following description: “On applications that do not use an engine coolant temperature (ECT) sensor, the CHT sensor is used to determine the engine coolant temperature.
What does 3 07 mean on a thermometer?
Looking at the chart in Figure 4, you will notice that there is the potential for confusion outside of the overlap zone. A 3. 07 volt reading could mean 110°C (230°F) while 3. 26 volts could mean 20°C (68°F). It all depends on whether (weather) you are in the cold range of the hot range.
