What Is Code P0116 Mean?

P0116 is the OBD-II generic code that indicates the engine control module (ECM) ECT monitor has read that the ECT sensor range or the sensor performance is not as the ECM expected when starting from a cold start and warm shut down, to the next cold start.Mar 11, 2016

How do I fix P0116 code?

What causes P0116 code?

The Engine Coolant Temperature Sensor converts the coolant temperature into a voltage that is high when the engine is cold and low as the engine warms up. Code P0116 is set when the Powertrain Control module sees irrational out of specification voltage signals from the coolant temperature circuit.

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.

Can a temp sensor affect engine starting?

The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.

Can you clean a coolant temperature sensor?

In most cases, sensors for your automobile will need to be replaced if they fail, but depending on the type of sensor and its location or function, some can be cleaned and reused. Sensors can come in many types and are used for a variety of systems on modern cars.

How do you check a temperature sensor?

Gently lower the end of the sensor into the water until the entire device is fully submerged. Wait a minute or so for the screen to give you a reading of the cold water. Once you have a reading, write down the measurement for reference. A common reading for a temperature sensor in cold water is around 5 volts.

Can you run a car without a temperature sensor?

Most automobile mechanics will tell you it is not a good idea to drive your car without a thermostat installed. If your thermostat becomes stuck in the closed position, though, this will cause your engine to overheat and make driving your car impossible.

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. Then close the drain valve. This will minimize coolant waste when you remove the sensor.

What causes a coolant temperature sensor to go bad?

One of the common problems is; when the sensor has a, poor connection inside or in the connector. This causes interruptions in the signal to the (PCM) and the (PCM) sets the fault. In some vehicles, symptoms of this problem show up as, erratic readings of the temperature gauge.

Can a coolant temp sensor cause starting problems?

Bad coolant temperature sensor causes cold starting problems

If you have to pump the gas pedal in the morning to keep your car running, you may have a bad engine coolant temperature sensor. … You can have a bad sensor even without a “check engine” light or trouble code.

How long does it take to replace a coolant temperature sensor?

The actual process of replacing the coolant temperature sensor is extremely simple. However, the difficult work comes in the preparation of the cooling system – both before and after. Tip: This job should only be completed when the engine is cold and has not been running for a minimum of one hour.

What does code po118 mean?

P0118 is the OBD-II generic code that indicates the Engine Control Module (ECM) has seen the ECT sensor output go more than 4.91 V or less than -40°C (-40°F).

What does the cylinder head temperature sensor do?

Thermometrics Cylinder Head Temperature Sensor is designed to take the place of one of the cylinder head bolts on a diesel engine. The sensor’s purpose is to measure the cylinder head temperature and to signal the vehicle’s operator if an engine overheats (that is, if an engine over-temperature is taking place).

Can you drive with a P0128 code?

You may drive your vehicle with a P0128 trouble code. You will not notice any issue except for maybe the temperature gauge never reaching normal levels, and possibly the Check Engine light being illuminated.

How do I fix a code po128?

What repairs can fix the P0128 code?
  1. Replacing the thermostat (most common repair)
  2. Replacing the coolant temperature sensor, or the wiring and connector associated with the sensor being damaged.

How do I clear P0128 code?

Can low coolant cause P0128 code?

Low engine coolant can alter the engine running temperature enough to signal trouble code P0128. Your intake air temperature sensor, coolant temperature sensor and coolant fan could also signal this trouble code, so these should be inspected after you look over your thermostat and coolant level.

Can a bad coolant temp sensor cause AC not to work?

Another symptom of a bad or failing ambient temperature sensor is inconsistent cooling. … If the ambient temperature sensor fails or is sending out an inconsistent signal, then the AC system may have trouble maintaining cool and comfortable cabin temperatures.

Does the coolant temp sensor control the fan?

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 low coolant cause P0117 code?
