277C - P114A
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 |
