2013-02-14· The coolant temp sensor measures resistance and sends that back to the ecu. Different temps = different resistances. At different resistances, the ecu will tell the injectors to run at a higher duty cycle or a lower duty cycle (basically letting more or less fuel into the combustion chamber). This is done because at a colder temperature, the car needs to run more rich in order to fire up and ...
2021-02-01· It is possible to drive a vehicle with a faulty coolant temperature sensor as the management system defaults to a static reading. A vehicles coolant sensor is a critical component used by the engine management system. It directly effects, cooling and fueling of the engine and therefore effects how the engine performs.
2017-01-13· It sounds like in your case, the coolant sensor is either incorrect, or you have two failed sensors - it happens, although not all that often. Plugged in, the sensor is sending a signal for an extremely cold setting, with a very rich mixture as the result. Disconnecting the sensor may be getting you a default setting, and fuel mixture, that is much better for the engine’s performance. I ...
2021-06-27· Can a car drive with a bad coolant sensor? Maybe, here is why. Two types of coolant sensors are common. First is a coolant temperature switch. Second, is a coolant temperature sensor. A switch is used to turn things on and off. Those things can be...
2013-06-17· 2013-07-03· Worried about longevity. Usually the Coolant Temp Sensor is used for the gauge for fuel trims for cold start enrichment, and fan control. Since the Thermostat and water pump are mechanical the engine will still cool. you will be fine driving until the replace the sensor…
2021-06-15· The average coolant temperature sensor replacement cost is between $50 and $250, depending on the car model and labor costs. A coolant temperature sensor costs $30 to $100, and the labor costs $20 to $150. The coolant temperature sensor itself is often quite cheap and you can often find them around $40 for a quality one.

Can you drive without a coolant temperature sensor? What Happens If You Unplug The Coolant Temp Sensor?Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. The engine light may not come on imminently but a DTC (Diagnostic Trouble Code) will be logged in the PCM.
2021-04-27· Can you drive without a coolant temperature sensor? Unplugging the engine coolant sensor while the car is running will likely cause the engine to stumble and run rough. Unplugging the engine coolant temperature sensor before starting the engine may result in a no start, especially likely on a cold morning.

2017-01-12· The motor runs very rich when cold and floods immedialty. This immediately stops if I unplug the new coolant temp sensor. I will leave it unplugged for about 10 min, or until the motor is at normal operating temp, and re plug the senor back, and it runs like a new motor.
I was driving my 2004 Mazda MPV and I noticed that my engine temperature sensor in the instrument panel went to zero. I noticed but kept driving. I stopped at a grocery store turned off the engine and went shopping. When I got back on the Mazda it...
