Oil sensor, ME-SFI fault code description, - AD07.61-P-4000-60L

			Oil sensor
1	Fault code		P2039 Oil level signal implausible (-)
	( Display on generic scan tool)		P2040 Oil quality signal implausible (-)
			P2041 Water in engine oil (-)
			P2076 Oil temperature signal implausible (-)
2	Fault storage		After expiry of test duration and fault
2	Activation of the engine diagnosis indicator lamp (EURO3/4) or CHECK ENGINE (MIL) malfunction indicator lamp		No activation
3	Checking frequency		Continuous
4	Checked signal or status		Signals from oil sensor, water in engine oil
5	Fault setting conditions		The duty cycle of a signal must not be smaller than 17 % or larger than 83 %.
		Signals from oil sensor	The dielectric constant of the engine oil is or was temporarily greater than 5.8 (e.g. due to excessive water in the engine oil, without water approx. 2.3 to 4.0).
		Water in engine oil
6			If all the signals are defective at the same time, first check the signal line for an interruption or short-circuit. If the lines are in order, replace the oil sensor. If only one or two signals are defective, replace the oil sensor. If signals are defective and if at the same time the fault "Water in engine oil", fault code P2041 is output, first replace the engine oil. If the dielectric constant of the engine oil is greater than 5.8 a safe function of the capacitive measurement is no longer guaranteed.
