P0118 Engine Coolant Temperature Circuit High Input

[typefilipino]

pulled out my obd2 reader, gave me the code, searched it up, dont know what to do bout it.. checked my coolant, its not low, sometimes when i start my car, it idles weird at 1.5 rpm.. any suggestions? pictures ? anything? 8)

run the car with the radiator cap off make sure there isn't any air that needs to be burped out of the system. if not replace the sensor and clear the code. and reburp the air out. the idle problem sounds like a faulty coolant sensor

does it just rev to 1500 when its cold?

its warm, it just revs up to 1500 by itself sometimes at the stoplight, parking lot etc lol

just change the sensor they arn't expensive.
