How does a one wire coolant temp sensor work?
The sensor works by measuring the temperature that’s being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. As the control system receives the temperature from the CTS, it may trigger the cooling fan to either shut off or turn on.
Can you splice a temperature sensor?
Thermal-couples can be bought as a spool of cable that contains the pair of wires. This way, they can be cut to any desired length based on need. Either type can be spliced (or lengthened) without very much fear.
Can you extend a temperature sensor cable?
The extension will cause the resistance of the lead wires to affect the display temperature, so use lead wires with thick conductors. Be careful of the cable routing because extending the lead wires makes the Sensor more susceptible to the effects of electrical noise.
Can you splice a thermistor?
You will have to splice the wires. The best way to do this is with a bell connector, which is just a one-ended squeeze connector. You will have to have a tool to correctly squeeze the connector to make a good connection.
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.
What does the temp sensor do?
A temperature sensor is a device that gathers data concerning the temperature from a source and converts it to a form that can be understood either by an observer or another device. These sensors come in many different forms and are used for a wide variety of purposes, from simple home use to extremely accurate and precise scientific use.
Where is the coolant temperature sensor located?
The engine coolant temperature sensor is usually located on the engine block or cylinder head . It is often installed on a plastic hose on the coolant’s inlet. Different brands and car manufacturers have different ways of placing the coolant temperature sensor depending on the car design.
What is a 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.
