What is the Cylinder Head Temperature Sensor every about?

Your engine control module monitors and regulates nearly every one of your engine performance based upon temperature measurements. Throughout cold conditions or cold starts, the engine requires more fuel to operation well and maintain a higher idle speed. When the engine is warm, less fuel is required for the engine to run smoothly and also efficiently. There are a couple of methods automobile makers have actually utilized to recognize engine temperature, through the most typical being a coolant temperature sensor.

The coolant temperature sensor consistently monitors the engine’s heat based on the temperature that the fluid circulating in the block and also reports it to the engine manage module. The ECM adjusts EGR flow, engine timing and many other things based upon this information. Because that vehicles not equipped with a coolant temperature sensor, a cylinder head temperature sensor, or CHT sensor, is employed. It is composed of 2 resistors encapsulated in one sensor to maintain a vast operating temperature of -40F come 260F. One resistor monitors the high temperatures and also the other, the low temperatures, and reports castle in a voltage reading to the ECM. From this reading, the engine control module infers the coolant temperature and bases that is adjustments on it. If the CHT sensor isn’t analysis correct voltages, you can experience problems ranging from lengthy cranking times and low idle speed on cold starts come stalling and also hesitation on acceleration while the engine is warm.


Keep in mind:

The cylinder head temperature sensor doesn’t measure up the coolant temperature. Instead, it steps the metal temperature and also infers the coolant temperature indigenous that.Allow the engine come cool off before servicing the cylinder head temperature sensor.

How it"s done:

The cylinder head temperature sensor is confirmed that it needs to it is in replaced. The rubber head seal and also connector are eliminated to access the sensor.

The defective cylinder head temperature sensor is gotten rid of with a deep well socket come unscrew the sensor native the cylinder head.

The new cylinder head temperature sensor is set up into the head and also tightened to specifications.

The electrical connection and also rubber seal room reinstalled. The cylinder head temperature sensor is tested for procedure with a scanner.

The vehicle is road tested to ensure ideal operation that the cylinder head temperature sensor.


Our recommendation:

The CHT sensor need to last the life of your vehicle. That is an electric component and can failure unexpectedly, and also if that does, the will should be changed by among our expert technicians. If you doubt you have actually a CHT sensor problem, have a trained technician diagnose the difficulty as security the sensor is tricky and requires certain knowledge.

How necessary is this service?

The cylinder head temperature sensor deserve to dramatically affect your engine’s power if it is faulty. It may reason running problems while you are driving in traffic including stalling and also hesitation. Have actually it diagnosed and repaired as quickly as feasible so girlfriend don’t put yourself in a potentially difficult or dangerous control situation.
