How can I test the coolant temperature sensor?
Testing the ECT/CHT sensor Resistance: One way is to measure the resistance of the sensor at different engine temperatures and compare the readings to the specifications listed in the service manual. Measuring the resistance of the Engine coolant temperature (ECT) sensor.
What should I do if my engine temp sensor is not working?
Locate the sensor away from the engine heat and start the engine and run it untill it’s hot. If the engine doesn’t act up in the same amount of time it’s a good bet the sensor is failing. I {Heart} Hookers.
How does the cylinder head temperature sensor work?
Some cars use a cylinder head temperature or CHT sensor instead of, or in addition to the ECT sensor. The CHT sensor (see the photo) works the same way, but it measures the temperature of the cylinder head metal and is not immersed in coolant. This allows the CHT sensor to measure the temperature of the engine correctly even with loss of coolant.
How to test the ECT / CHT sensor resistance?
There are several ways to test the ECT sensor; you can find the correct way in the service manual. Testing the ECT/CHT sensor Resistance: One way is to measure the resistance of the sensor at different engine temperatures and compare the readings to the specifications listed in the service manual.
What does the Check Engine light on the coolant temperature sensor do?
Check Engine Light comes on 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.
Locate the sensor away from the engine heat and start the engine and run it untill it’s hot. If the engine doesn’t act up in the same amount of time it’s a good bet the sensor is failing. I {Heart} Hookers.
How much does a coolant temperature sensor cost?
$92.73 – $160.32. Price range for all vehicles. Average rating from 17,525 customers who received a Change Oil and Filter. 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.
What happens to the engine temp sensor on a Harley Davidson?
Also with the sensor removed the engine idle will remain high, in cold idle mode. Ahh sensors , ya gotta love failing sensors on ALL the newer Harley’s . Sometimes newer doesn’t equate to better , especially when it comes to Harley’s !
What happens to the p0117 code when coolant is warm?
As the temperature of the coolant changes, the resistance of the sensor changes. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a signal voltage lower than the normal operating range of the sensor then P0117 code will set.
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.
How does the coolant temp sensor work on a PCM?
When the PCM senses this high voltage input, it will translate this voltage input to a coolant temperature of -46° F (-50° C). Coolant temp sensor’s wires have an ‘open-circuit’ problem (usually due to a cut wire).
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.
What causes a check engine light on the ECT sensor?
Many Check Engine light codes related to the ECT sensor could also be caused by other reasons, such as a bad thermostat or issues with the cooling system, including even a leaking head gasket. The problem must be properly diagnosed.
How to replace the coolant temperature sensor on a Saturn?
1 Park your vehicle in a safe location on even ground. 2 Locate the coolant temperature sensor in the hood area. 3 Identify the engine coolant temperature sensor as a black and copper-colored prong sticking out of the engine block. 4 Disconnect the sensor from the engine using a ratchet.
When to replace the temp sensor on your car?
The temperature sensor alerts the engine control computer when the engine is overheating. Replacing the temperature sensor is strongly recommended if you suspect the sensor is damaged. Park your vehicle in a safe location on even ground.
Where is the coolant sensor on my car?
Look just below where the radiator hose connects to the engine block and you should see the sensor. Identify the engine coolant temperature sensor as a black and copper-colored prong sticking out of the engine block. The sensor will also be attached to two wires.
