Causes And Fixes P0118 Code Engine Coolant Temperature P0138 code: o2 sensor circuit high voltage (bank 1, sensor 2) the p0138 code indicates high voltage in the o2 sensor circuit. learn its causes, symptoms, and fixes to keep your vehicle running smoothly. The engine coolant temperature (ect) sensor monitors the fluctuations in the temperature of the engine coolant. 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.
P0118 Engine Coolant Temperature Ect Sensor Circuit High O How to fix a p0118 code: engine coolant temperature sensor 1 circuit highthe engine coolant temperature sensor (ect) reports the temperature of the engine to. P0118 will set if the voltage measured by the engine computer (ecm pcm) is higher due to high resistance (low voltage high temp [warm engine]) like a disconnected ect sensor. the engine computer checks for a resistance corresponding to a very low engine coolant temperature. the check is enabled whenever the ecm is powered. Causes. a code p0118 may mean that one or more of the following has happened: a bad connection at the sensor. 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 pcm (less likely) a bad temperature sensor (shorted internally). The obd ii generic code p0118 means that the engine control module (ecm) saw that the ect sensor output was greater than 4.91 volts or less than 40 degrees fahrenheit. the temperature of your car’s engine is read by a sensor inside the car. this information is sent to the ecm so that it can adjust the fans and other cooling devices as needed.
P0118 Fault Code In Ford P0118 Engine Coolant Temperature Cir Causes. a code p0118 may mean that one or more of the following has happened: a bad connection at the sensor. 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 pcm (less likely) a bad temperature sensor (shorted internally). The obd ii generic code p0118 means that the engine control module (ecm) saw that the ect sensor output was greater than 4.91 volts or less than 40 degrees fahrenheit. the temperature of your car’s engine is read by a sensor inside the car. this information is sent to the ecm so that it can adjust the fans and other cooling devices as needed. 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 p0118 indicates a high voltage input from the coolant temperature circuit to the pcm. P0118 is a generic diagnostic trouble code (dtc) defined as “engine coolant temperature sensor circuit high input”. it applies to all vehicles from 1996 to current models. the engine coolant temperature sensor (ect sensor or coolant temp sensor) is a thermistor in the coolant passage inside the cylinder head located on top of the engine block.
