What is the p0118 coolant temperature sensor circuit?
P0118 Engine Coolant Temperature Sensor Circuit Hi Voltage: diagnostic checks for a resistance corresponding to a very low engine coolant temperature. Engine control module (ECM) or PCM (powertrain control module) supplies 5 V to the ECT sensor signal circuit and a ground for the low reference circuit.
How does the coolant sensor work on a jeep wranger?
Coolant temperature sensor test and change for the Jeep Wranger. Coolant Temperature Sensor monitors the temperature of the water in the engine. The PCM uses this temperature reading to adjust the fuel injection and timing. In some cases the PCM uses the reading from the sensor to turn on the electric cooling fan if so equipped.
What are the symptoms of the p0118 code?
What are the symptoms of the P0118 code? The ECM turns the Check Engine Light on and goes into failsafe mode, substituting input to 176 deg F. The engine may have a hard start when engine is cold, and start normal when warm. The engine may run rough and hesitate until the engine warms up.
What happens when your coolant temperature sensor is bad?
The engine is very sensitive to wrong air-fuel mixtures at idle and this is a condition when you might notice that something is wrong with your engine coolant temperature sensor. The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically.
What does it mean when your coolant sensor says p0118?
A code P0118 may mean that one or more of the following has happened: An open in the ground circuit between the ECT sensor and the PCM A short in the voltage feed between the sensor and the PCM A bad temperature sensor (shorted internally) First, if you have access to a scan tool, check the reading of the coolant sensor.

What causes p0128 in a Jeep Wrangler?
The most common cause for P0128 in a Jeep 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, however, you should be extremely careful when doing this as you could be burned.
The engine is very sensitive to wrong air-fuel mixtures at idle and this is a condition when you might notice that something is wrong with your engine coolant temperature sensor. The engine coolant temperature sensor can have a hard impact on the air-fuel mixture. A bad air-fuel mixture can also cause the engine performance to drop drastically.
What does the ECT code p0118 mean?
Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit. (typically over 4.7V) What Are the Symptoms of Code P0118?
When does the engine coolant temperature sensor set?
The engine computer checks for a resistance corresponding to a very low engine coolant temperature. The check is enabled whenever the ECM is powered. If the resistance of the sensor is greater than a calibration for a period of time P0118 will set.
Why does my 2002 Mini Cooper p0118 still come back?
2002 Mini Cooper S P0118 is still came back after I have replaced a PCM sensor. Does outside temperature relate to this problem where I have a bad outside temp TC (fluctuate reading on the gauge). Engine temp is reading normal (at the mid range). What should I do next to solve it.

What causes the p0118 OBD-II trouble code?
All our repairs are backed by our 12-month / 12,000-mile warranty. 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 causes the P0118 code?
Where is the coolant temperature sensor located in an engine?
P0118 – Engine Coolant Temperature Sensor 1 Circuit High Theory of Operation The Engine Coolant Temperature Sensor (ECT) is located near the thermostat housing and is used to measure the engine coolant temperature. The Engine Coolant Temperature Sensor receives 5-Volts and a sensor ground from the PCM.
What should the voltage be on a p0118 Chevrolet?
When the coolant is warm, the sensor resistance is low. The signal voltage is pulled down a greater amount; therefore, the PCM senses a low signal voltage (high temperature). At normal operating temperature, the voltage should measure about 1.5-2.0 volts at the PCM. P0118 CHEVROLET More Information.

What does the code p0118 mean on the ECM?
This data is sent to the ECM, which uses this data to regulate the air to fuel ratio, cooling fans, and ignition spark timing needed by the engine. Code P0118 is the result of the ECT sensor indicating a high voltage input from the coolant temperature circuit. (typically over 4.7V)
What does the code p0118 mean on a Chevy Spark?
P0118 is a common OBDII trouble code. It is a general code, which means that it’s going to have the same meaning for the Chevy Spark as it would any other vehicle. This code is thrown when the resistance coming from the coolant temp sensor does not change as the vehicle warms up. P0118 is sometimes accompanied by noticeable symptoms.
What does the p1296 coolant temperature sensor do?
