What causes a p0116 coolant temperature code?
There may be no noticeable symptoms if the problem is very intermittent, however the following may occur: MIL (Malfunction Indicator Lamp) illumination Potential causes of the P0116 code include: An example of an Engine Coolant Temperature ECT sensor If there are any other ECT sensor codes, diagnose them first.
What does p0116 mean on a Toyota Corolla?
Took the car to the dealer and the code is as follows: P0116 Coolant Temperature Circuit Rank P2616 ECM/PCM Engine Off. Found what the P0116 Code means but have not found the meaning of the rest “Rank P2616 ECM/PCM Engine Off”. This is a Toyota Corolla, Base Model, Automatic, 4 cyl, with 25,000 m…
Why does the PCM set a p0116 code?
When coolant is warm, the sensor’s resistance is low and the PCM will see a high temperature. The PCM expects to see slow resistance changes on the ECT signal circuit. If it sees a quick change in voltage that isn’t consistent with an engine warming up, this P0116 code will set. Or if it sees a lack of change in ECT signal, this code may set.
How does the PCM work when coolant is low?
The PCM monitors the reading and determines coolant temperature in order to perform essential engine fuel management. When engine coolant is low, sensor resistance is high. The PCM will see a high signal voltage (low temperature). When coolant is warm, the sensor’s resistance is low and the PCM will see a high temperature.
What does DTC p0116 mean for engine coolant?
If the startup coolant temperature minus the startup intake air temperature is greater than a calibrated value, then the diagnostic will indicate a fault and set DTC P0116 and puts on the malfunction indicator lamp or MIL. The MIL is also called the Check Engine Light and the Service Soon Engine light. What are the common causes of code P0116 ?

When does DTC p0116 diagnostic will not execute?
DTC P0116 diagnostic will not execute unless: there are no IAT (Intake Air Temperature) DTCs ( P0112 or P0113) sensor faults, there are no engine coolant sensor high or low input faults ( P0117 or P0118 ), the ignition off timer has not failed (DTC P1683 ), and the startup IAT is greater than a calibrated value.
What does it mean when your car says p0171?
Since the error code p0171 means the presence of a lean mixture in a vehicle, various sensors may cause the code. In order to diagnose this code, do the following: This is part of the troubleshooting process, with which you turn on ignition while not wanting to achieve low voltage.
What causes a p0107 DTC to be set?
A P0107 DTC is set when the PCM sees that the MAP signal voltage is less than .25 volts which is too low. Anytime the MAP sensor signal is low the vehicle will likely have a very difficult time starting. Other symptoms may include: MIL (Malfunction Indicator Lamp) illumination
There may be no noticeable symptoms if the problem is very intermittent, however the following may occur: MIL (Malfunction Indicator Lamp) illumination Potential causes of the P0116 code include: An example of an Engine Coolant Temperature ECT sensor If there are any other ECT sensor codes, diagnose them first.

What does coolant temperature sensor circuit range mean?
Engine Coolant Temperature (ECT) Sensor Circuit Range/Performance What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to all 1996-newer vehicles (Ford, Hyundai, Kia, Mazda, Mercedes-Benz, etc.). Although generic, the specific repair steps may vary depending on make/model.
What happens to the ECT signal when coolant is warm?
When coolant is warm, the sensor’s resistance is low and the PCM will see a high temperature. The PCM expects to see slow resistance changes on the ECT signal circuit. If it sees a quick change in voltage that isn’t consistent with an engine warming up, this P0116 code will set.
What should the ECT reading be on a cold engine?
On a cold engine, it should match the IAT reading or should be equal to ambient (outside) temperature reading. If it does match the IAT or ambient temp, check the freeze frame data on your scan tool (if equipped). The saved data should tell you what the ECT reading was when the fault occurred.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
What’s the name of the coolant temperature sensor?
Coolant temperature sensors are also known as engine coolant temperature sensors or ECT sensors. The principle working of this sensor involves the use of an electrical resistance which measures the temperature of the coolant.
What are the different types of engine temperature warning systems?
There are several types of engine temperature warning systems on vehicles. A temperature gauge that has a red light at the hot end of the temperature range A red or yellow light that will come on and even blink when the engine temperature is too high A messaging system that will flash “engine overheating” in the driver information center.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
DTC P0116 diagnostic will not execute unless: there are no IAT (Intake Air Temperature) DTCs ( P0112 or P0113) sensor faults, there are no engine coolant sensor high or low input faults ( P0117 or P0118 ), the ignition off timer has not failed (DTC P1683 ), and the startup IAT is greater than a calibrated value.
What is the error code for engine coolant temperature?
Error Code P0116: Engine Coolant Temperature (ECT) Sensor Circuit Range/Performance Basically, it refers to a PCM (powertrain control module, also known as ECM or electronic control module) reading irrationally or out-of-specifications voltage signals coming from the ECT. The job of the ECT sensor is to measure the rise and fall of the ECT.
