Where is the coolant temperature sensor on a car?
Many cars have more than one coolant temperature sensor. In most cars, the primary ECT sensor (ECT sensor 1) is installed near the thermostat in the cylinder head or block or on the thermostat housing. A second coolant temperature sensor could be installed in another part of the engine, or in the radiator.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
Can a car have more than one coolant sensor?
Some vehicles may have more than one temperature sensors, as sometimes different sensors are used to send the signals to the dashboard and the control unit of your engine system. This is optional and a manufacturer can use only one coolant temperature sensor to send the signals to both of these desired receivers.
How much does it cost to replace a coolant temperature sensor?
Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
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.
Where is the temperature sensor located?
Usually, this sensor is located behind the grille but is in front of the radiator and radiator support. This is the best location for the sensor as it is away from the heat of the engine and can accurately read the ambient temperature of the air around it; that is the temperature of the air entering the intake manifold at the front of the engine.
What does a bad coolant temperature sensor do?
If the coolant temperature sensor goes bad it can send a false signal to the computer and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail and send a permanently cold signal to the computer.
What are the symptoms of a bad coolant temperature sensor?
Another symptom of a problem with the coolant temperature sensor is an overheating engine. The coolant temperature sensor can also fail in a manner that causes it to send a permanently hot signal. This can cause the computer to incorrectly compensate for a lean signal, which can result in overheating, and even misfires or engine ping.
Why is the temperature sensor on my car not working?
One of the common problems is when the sensor has poor connection inside or in the connector or in the wiring harness. This causes interruptions in the signal to the PCM and the PCM sets the fault. In some cars, symptoms of this problem show up as erratic readings of the temperature gauge.
Where are the oil control valves on a Kia Forte?
CVVT Oil Control Valve (OCV) [Bank 1 / Exhaust] 21. Variable Intake Solenoid (VIS) Valve 22. Variable Charge Motion Actuator (VCMA)
Where is the coolant temperature sensor located on an engine?
The readings produced from the coolant temperature sensor are transmitted to the engine control unit, where they are utilized as data for regulating and maintaining the proper ignition time and the optimal fuel injection through the computerized approach. The engine coolant temperature sensor is usually located on the engine block or cylinder head.
Where can I find the coolant temperature sender?
Locate the Coolant Sensor There are usually only three places the coolant temperature sender can be located which is: In or near the thermostat housing, in the cylinder head or in the intake manifold. To find where the sensor is located check Google images or you can use an online service like Mitchell1.
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
Unscrew the ECT sensor in an anticlockwise direction, similar to how a spark plug is removed. Install the new sensor and reconnect the connector cable. The average replacement cost of the Coolant Temperature Sensor is between $100 and $220. The labour cost is between $40 and $140 while the part itself costs between $50 and $80.
The engine coolant temperature (ECT) sensor is a thermistor screwed into a coolant passage in the cylinder head. Sensor resistance is high when coolant temperature is low and resistance drops when coolant temperature increases. The powertrain control module (PCM) provides a 5 volt reference and a ground to the sensor.
Can a bad coolant sensor cause a car to not start?
Some cars use the engine coolant temperature sensor to control the electric cooling fans. You have two separate temperature sensors for the fans, dashboard gauge, and engine management in most cars. However, if your car has a single sensor, a bad engine coolant temperature sensor may result in your fans won’t start at all.
What to do if your coolant sensor does not have 5V?
If you do not have 5V ref. and/or ground continuity, check for these back at the PCM connector. If you have these at the PCM connector, then repair open or short between the PCM and the sensor. If you do not, remove the offending wire from the PCM and then check for proper voltage at the PCM pin.
On most vehicles, the coolant temperature sensor (CTS) can be found somewhere near the engine thermostat, which allows it to function optimally. The tip of the CTS is probably located right next to the engine coolant.
Where are the sensors on a GM 3.1L V6?
Common engine sensor and control component locations for the GM 3.1L and 3.4L V6 (3100, 3400) MAP Sensor. EGR Valve. EVAP System Purge Solenoid. Idle Air Control Motor (IAC). Throttle Position Sensor (TPS). Throttle Body. Intake Air Temperature Sensor (IAT). Fuel Pressure Regulator. Coolant Temperature Sensor (ECT). Mass Airflow Sensor (MAF).
What should I do if my temperature sensor is not working?
Generally speaking, if your sensor is not working, it will send a signal to the computer and your Check Engine light will be illuminated. If you see the Check Engine sign light up, take your car in for professional servicing right away. Replacing the Car Temperature Sensor . The sensor will eventually need to be replaced altogether after time.
