Information saved in	DME
Fault code	277C - P114A
Fault text	Oxygen sensor trim control diagnosis, bank 1
Fault description	Post Catalyst Fuel Trim Via Oxygen Sensor System Too Rich (Bank 1)
Condition for fault identification	Test condition: LEAN suspected under consideration of P-component ((6 (K_LA_TRIM_P_ANZ_MAX) + 3 (K_LA_TRIM_DIAG_P_SCHW P-spikes)) leads to deliberate RICH/LEAN control activation; if the pre-catalyst and post-catalyst oxygen sensors respond accordingly a trim control error is recognized.
	Terminal condition: Engine running
	Voltage condition: None
Condition for fault memory entry	None
Action in service	1) Check intake and exhaust systems for leaks; incl. HFM operation/ ..if no fault is present..
	2.) Conduct oxygen sensor test routine
	3.) If the test does not produce any results and the trim control error is still present ->Replace the sensor before the catalytic converter
Fault effect and breakdown warning	MIL on after engine runs 2x / no effects on drivability
Driver information	Warning light: MIL
Service instruction	None
