ME-SFI fault code description for fuel injectors - AD07.61-P-4000-10A

1	Fault code		P0201 Cylinder 1 (Y62y1) P0202 Cylinder 2 (Y62y2) P0203 Cylinder 3 (Y62y3) P0204 Cylinder 4 (Y62y4) P0205 Cylinder 5 (Y62y5) P0206 Cylinder 6 (Y62y6)
2	Error storage		after expiry of test duration and fault
	Activation of engine diagnostics malfunction indicator lamp (EURO3/4) or CHECK ENGINE (MIL)		after two successive driving cycles with faults
3	Frequency of test		Continuously
4	Checked signal or status		Current/voltage check at each fuel injector
5	Fault setting conditions		Voltage < 2.5 V
	Limit values		Current > 4.2 A
		Short circuit to ground	No voltage at fuel injector
		Short circuit to + 12 V	approx. 4 - 8 V at unloaded output of ME-SFI control module
		Open circuit	approx. 1 s
	Test duration
6	Test prerequisites		Battery voltage between 8 -17.1 V
7			The actuation of each fuel injector is inspected for signs of open and short circuits (to ground or battery voltage). When the output stage is in locked status a short circuit to ground and an open circuit can be detected, whereas for a conducting output stage a short circuit is recognized to the battery voltage. If a malfunction occurs the output stage is immediately deactivated.
8			If there is a short circuit to ground the corresponding fuel injector is always open.
