RESOLVED: SES CODE P1092 [P1190] [BMW 235]

[Tony C.]

I was another victim of the P1092 code retrieved using OBD Fusion. After finding this thread I was able to sort it out and get the problem corrected by replacing the Bank 1, Sensor 2, sensor. Using INPA I had the following codes in the Error Memory Report (translated from German):
235 Lambda trim control pre-cat bank 1
215 Post-cat probe, activity check BK1, (probe 3)
222 Lambda control not active after a specified time

I’m not sure if this is useful information but the resistance of the heater element in the new sensor measured 2.8 Ohms at room temperature and the old sensor seemed to be quite erratic.
