Where is the temp control sensor located?
Where is the temp control sensor located?
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 are the signs of a failing temperature sensor?
Following are the significant symptoms of a bad coolant temp sensor:
- Check Engine Light.
- Engine Overheating.
- Poor Fuel Economy.
- Poor Engine Performance.
- Broken Water Pump.
- Control of Cooling Fan.
- Black Smoke From Exhaust Pipe.
How do you replace the temperature sensor?
- With the engine and coolant entirely cooled down, disconnect the battery.
- Remove any plastic engine covers.
- Locate the coolant temp sensor.
- Partially drain the cooling system, or perform a coolant flush, if it is due.
- Disconnect the electrical connector from the sensor by pushing on the tab and pulling the connector.
Can I change coolant temperature sensor without draining coolant?
Do you need to drain coolant to change coolant temperature sensor? Open the radiator valve and drain about two to three quarts of coolant. You only need to remove enough to drop the level below the sensor.
How long does it take to replace temperature sensor?
How long does it take to replace a coolant sensor? In most cases, it is 5 to 10 minutes, once you have the right wrench in your hand and the sensor in the other.
What happens when a temperature sensor goes bad?
If the coolant temperature sensor malfunctions, it can transmit a false signal to the computer. And the response of the computer may unbalance the timing and fuel calculations. It is also common for a coolant temperature sensor to fail without warning and send permanently cold signals to the computer.
How much does it cost to replace a temperature sensor?
The average price for an engine temperature sensor replacement is between $150 and $193. Labor costs are between $82 and $105 while parts are between $66 and $88. Taxes and fees aren’t included in the estimate.
Can a coolant temperature sensor cause rough idle?
Can a bad coolant temp sensor cause rough idle? Yes, due to the false signal sent to the car computer, it will adjust the air-fuel mixture. The supplied mixture will not be enough and result in vibrations and shaking at idle or low-speed maneuvers and lead to other strange behavior and loss of engine power.
Can you drive with a bad temp sensor?
Yes, you can drive with a bad coolant temperature sensor. When the coolant temperature sensor goes bad the ECU of the car defaults to a static reading. But it is not recommended to keep driving with a bad engine coolant temperature sensor since it performs critical cooling, heating, and fuel adjustment functions.
Is there a fuse for coolant temperature sensor?
There isn’t one per se. There will be a fused wire with voltage to the instrument cluster (your owners manual should indicate which fuse), but the temperature sensor is providing a variable “resistance to ground,” which the temperature gauge in the dash is reflecting.
