Boost pressure control pressure transducer, ME-SFI fault code description - AD07.61-P-4001-02M

		Boost pressure control pressure transducer (Y31/5), actuation
1	Fault code (Fault code according to OBD)	P2035 (-)
2	Fault storage	After expiry of test duration and fault
	Actuation of engine diagnosis indicator lamp (EURO4) or CHECK ENGINE (MIL)	no activation
3	Checking frequency	Continuous
4	Checked signal or status	Current/voltage test on boost pressure control pressure transducer
5	Fault setting conditions
	Short circuit to ground	Voltage lower than 4 volts
	Short circuit to positive	Current higher than 4.2 A
	Open circuit in wiring	No voltage on boost pressure control pressure transducer ca. 4 to 8 V on the under no load output of the ME control unit
6	Check prerequisites	Battery voltage between 8 and 17 V
7		Actuation is checked for a line interruption and short-circuit (to ground or battery voltage). A short circuit to ground and a cable breakage will be recognized when the output stages are locked, while a short circuit to the battery voltage is recognized when the output stages are conducting. The output stage is immediately no longer activated when a fault arises. No boost pressure control is possible as a result and only the basic charge pressure (ca. 300 mbar) is achieved (loss of power).
