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
	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
	Signals from oil sensor	The duty cycle of a signal must not be smaller than 17 % or larger than 83 %.
	Water in engine oil	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).
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.
