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
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.
To replace the ECT sensor, you are going to pay, on average, $95-$140. How much you pay depends on the type of car you own and where you go for servicing. Each mechanic has their own rates, and they may be getting their parts from a variety of vendors, which can change how much the parts cost you.
The most common cause for P0128 is the engine coolant thermostat is stuck open. A simple way to diagnose this is to feel the radiator hose and monitor how hot the temperature of the coolant is when it starts flowing through the radiator hose.
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.
The sensor will not cause a no start. It could cause a hard start and a rich or lean condition only.
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.
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.
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.
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.
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.
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.
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).
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).
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.
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.
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.
There are a lot of issues that could trigger the engine code P0117. Below are just some of the possible causes of P0117: Defective engine coolant temp sensor. … Damaged or corroded engine coolant temp wiring or connection.
P0113 is the OBD-II generic code that the engine control module (ECM) has recorded the IAT sensor output above expected sensor range.
The Engine Coolant Temperature or ECT sensor is often referred to as the master sensor, and is one of the most important sensors in a modern engine. … If the engine is cold, the coolant sensor will tell the CPU to perform a closed loop operation and raise the idle speed to quickly heat up the engine.
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. … This also affects engine performance and fuel economy.
If the coolant temperature sensor malfunctions, it could cause your car engine to get overheated. While sometimes a faulty sensor sends a permanent cold signal to the engine, it can also send a permanent hot signal.
The most common sensors that will stop your car from starting include the camshaft sensor, the crankshaft sensor, the mass air flow (MAF) sensor, the manifold absolute pressure (MAP) sensor and the throttle position sensor.
