Where to find fault code p0115 Mercedes-Benz?
P0115 MERCEDES-BENZ Description This fault code is stored in the Engine Control Module (ECM) when the output from the engine coolant temperature sensor is not as expected or missing. The engine control module uses information from the intake air temperature sensor and engine oil temperature sensor to carry out a plausibility check on the signal.
What does the p0115 code on the dash mean?
This is because the P0115 code is referring to the ECT SENSOR, and the dash gauge is operated by, usually a one-wire SENDER. Basically a different sensor that the code doesn’t refer to.)
What happens to the p0115 coolant temperature sensor?
As the temperature of the coolant changes, the resistance changes on the ground signal to the PCM. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a voltage condition that seems abnormally low or high, P0115 will set. An example of an Engine Coolant Temperature ECT sensor
What was the problem with my 2006 ML 320d?
I bought my ML 320d new from Agnews dealership in 2006 in Belfast and during the first three year warranty the dealer claimed that the problem was relating to the air filter, rear brake sensor and finally the valve body in the gear box which they changed and charged me for when the warranty was up.
