Aging of O2 sensor upstream of TWC - fault code description ME - AD07.61-P-4000-07AB

		Aging O₂ upstream of TWC (G3/3, G3/4), cycle duration
1A	Fault code	P200D Right O₂ sensor upstream of TWC (G3/4) (P0133)
1A	( Readout on generic scan tool)	P2080 Left O₂ sensor upstream of TWC (G3/3) (P0153)
1B	Engines 112, 113 as of 1/01	P200D-[1] Right O₂ sensor upstream of TWC (G3/4), cycle duration too long (P0133)
1B	Fault code ( Readout on generic scan tool)	P200D-[2] Right O₂ sensor upstream of TWC (G3/4), cycle duration too short (P0133) P2080-[1] Left O₂ sensor upstream of TWC (G3/3), cycle duration too long (P0153) P2080-[2] Left O₂ sensor upstream of TWC (G3/3), cycle duration too short (P0153)
2	Fault storage	after expiry of test duration and fault
2	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	Signal for O₂ upstream of TWC
5	Fault setting conditions	Fault if the cycle duration is greater that 4 seconds (average value from 16 measurements).
6	Check prerequisites	engine speed approx. 1000 to 1800 rpm load approx. 15 up to 50% lambda controls enabled no high loading of activated carbon filter (lambda greater than 0.4) no fault in O₂ sensor heater no CAN fault
7		The average cycle duration is compared with an upper and lower limit value. In the case of the effect of simultaneous faults on the catalytic converter tighter limits apply so that a fault can be recognized more quickly.
