Where is the engine coolant sensor located?
The ECT sensor is located in the left of the cylinder head and is connected to the Engine Coolant Temperature Sensor. Underneath the air intake pipe and behind the right cylinder head is where the Engine Coolant Temperature Sensor is located.
Where is the temperature sensor on a 2002 Toyota Camry?
Its usually located very close to the water pump.
Where is the coolant temperature sensor located on a 2001 Toyota Camry?
This sensor is located on the bottom of the radiator opposite the coolant drain port. It works in conjunction with your car’s ECU (Electronic Control Unit) to adjust the air/fuel mixture based on the coolant temperature.
Where is the coolant temp sensor most commonly located?
Usually, the location of the coolant temperature sensor will be located directly behind the coolant pipe. In most modern cars and vehicles, this is present behind the right cylinder head that is located right underneath of the air intake pipe.
How do you know if your engine coolant is bad?
Symptoms of bad coolant
- Your coolant is dark, murky, smelly or full of debris. If your coolant looks (or smells) bad, it’s way past its useful life.
- Your temperature gauge reads higher than normal.
- Your engine overheats.
How do you change a water temperature sensor?
Replacing this sensor is an easy project that can be done in your own garage or on a flat driveway.
- Step 1 – Open Car Hood.
- Step 2 – Locate Coolant Temperature Sensor.
- Step 3 – Remove Lead Wire from Terminal.
- Step 4 – Loosen Coolant Sensor.
- Step 5 – Remove and Replace.
- Step 6 – Torque Sensor in Place.
- Step 7 – Reconnect Wire.
Can a bad coolant temp sensor cause rough idle?
HOW THE COOLANT SENSOR AFFECTS ENGINE OPERATION. A faulty coolant sensor that always reads cold may cause the fuel control system to run rich, pollute and waste fuel. A coolant sensor that always reads hot may cause cold driveability problems such as stalling, hesitation and rough idle.
Where is the coolant temperature sensor located in the engine?
Typically, the coolant temperature sensor is mounted in the engine block or cylinder head, near the thermostat or where the coolant flow is hottest. More than one coolant temperature sensor may be used on some systems to determine the temperature in different locations.
What happens if your car coolant sensor is not correct?
Your engine is overheating: If the engine’s computer doesn’t receive the correct temperature reading, it may not slow the ignition timing and turn on the cooling fans when necessary, causing the engine to overheat. If this happens, pull off the road and shut the car off as quickly as possible, as overheating can quickly kill your engine.
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.
