Fault code description for purge control valve, ME - AD07.61-P-4000-19L

		Purge control valve, voltage supply
1	Fault code ( Readout on generic scan tool)	P2026	(P0443)
2	Fault storage	after expiry of test duration and fault
	Actuation of the engine diagnosis indicator lamp (EURO3/4) or CHECK ENGINE (MIL) malfunction indicator lamp	following two successive driving cycles with faults
3	Checking frequency	Continuous
4	Checked signal or status	Voltage and current at purge control valve
5	Fault setting conditions  Limit values
	Short circuit to ground	Voltage lower than 4 volts
	Short circuit to +12 V	Current higher than 4.2 amps
	Open circuit in wiring	No voltage on the purge control valve,
	Checking duration	Approx. 4 to 8 V on under no load output of the ME control unit approx. 1 seconds
6		Actuation of the purge control valve is checked for to detect a line discontinuity and short-circuit (to ground or battery voltage). A short circuit to ground and a line discontinuity 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. If the purge control valve does not close (jams), the fault purge system has a gross leak will be stored.
