Where is the coolant temperature sensor located?

The CTS is normally towards the front of the engine, near the radiator or thermostat housing. Because it's a small component and is often located lower down inside the engine bay, you may need to use a light or torch to find it.

Can you drive with a P0118 code?

This trouble code will put your vehicle into a failsafe mode, which may cause your car's engine to hesitate and run rough. ... We recommend getting maintenance immediately as these conditions, if unattended for extended periods of time, may cause further damage to your vehicle.

What happens if you unplug the coolant temp 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.

Can a bad coolant temp 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.

What is code P0117 mean?

Code P0117 Definition

Engine Coolant Temperature (ECT) Sensor Circuit has lower than normal voltage.

Which part of the engine should the temperature sensor be fitted to?

The air temperature sensor is installed in the intake manifold and is used to measure the temperature of the engine intake air. The engine control module uses the air temperature and pressure to calculate the intake air mass.

Where is the temperature switch located?

Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it. Note: Some engines may actually have a pair of sensors—one sending information from the engine to the control unit, the other sending information from the control unit to the dash.

How much does it cost to replace ECT 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.

What sensor controls the temperature gauge?

To troubleshoot your car's temperature gauge, you need to know how it works. The temperature gauge reading starts out as a reference voltage that is sent to the coolant temperature sensor. This sensor is nothing more than a thermistor -- a variable resistor that changes resistance with temperature changes.

Will a bad coolant sensor throw a code?

A failed (ECT) sensor can send a false signal to the computer; and throw off the fuel and timing calculations. It is not uncommon for the coolant temperature sensor to fail; and send a permanently cold signal to the computer. This will cause the computer to think the engine is cold, even when it is not.

What does P2181 code mean?

What Does the P2181 Code Mean? Diagnostic trouble code (DTC) P2181 stands for “Cooling System Performance.” It is triggered when the powertrain control module (PCM) detects that the coolant temperature in the radiator and engine is outside of the normal range (too hot or too cold).

Can low coolant cause P0118?

Causes of Code P0118

If the problem is a rusty coolant system, that's the worst-case scenario. Even if you flush the coolant, the rust is likely to come back, which means you should replace various components.

What is the code P0128?

Code P0128 stands for Engine Coolant Temperature Below Thermostat Regulating Temperature. It means that the ECM/PCM has “noticed” that the engine coolant temperature is consistently running below thermostat regulating temperature. In other words, the engine is running cooler than it should.
