What should a temperature sensor read?
You should have a reading of approximately 2000 ohms. Check the warm sensor in your engine. You should see a much lower reading on the ohm meter. If not, then it is not working correctly.
How do I fix the engine code P0128?
What repairs can fix the P0128 code?
- Replacing the thermostat (most common repair)
- Replacing the coolant temperature sensor, or the wiring and connector associated with the sensor being damaged.
How do you fix a coolant temperature sensor?
Let’s Get Started
- Release the Cooling System Pressure. Locate and slowly remove the cooling system pressure cap to relieve the system of any residual pressure.
- Locate the Coolant Sensor.
- Remove the Electrical Connector.
- Remove the Coolant Sensor.
- Install the New Coolant Temperature Sensor.
- Refill the Cooling System.
Where is locate the coolant temperature sensor?
Locate the Coolant Temperature Sensor Depending on your particular vehicle model, you may find the sensor mounted on the cylinder head or intake manifold. Look for a large nut with an electrical connector on top, and two electrical wires coming from the connector – on most modern vehicles – or one wire – on Some sensors are buried under the intake plenum, specially on large trucks, and you need to remove the intake just to gain access to it.
Where do I find the coolant temperature sensor?
What is a Coolant Temperature Sensor and How Does It Work? A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
What are the symptoms of a bad coolant sensor?
Common symptoms of a bad engine coolant sensors are overheating, hard starting conditions, poor idle, check engine light ON and the electric fans do not work properly. The easiest way is to read the trouble code memory and check the value from the sensor, to make sure it’s a possible value.
What is the function of the coolant temperature sensor?
The coolant temperature sensor, also known as the coolant temperature switch, is an engine management system sensor that is used to monitor the temperature of the engine’s coolant. Most coolant temperature sensors operate using electrical resistance to measure the temperature of the coolant.
