Interesting Lambda problem
I'm having a bit of trouble with the two pre-cat lambdas on my car, and was wondering if one of you guys can make sense of it... Have the OBD II cable, with alfadiag, and about a month ago I replaced the sensor on bank 1 (closest to the battery), after another person's alfa diag connection told of a malfunctioning sensor. So got Alfa diag to DIY, and it informed me that there is no signal from the sensor on bank 2, so I replaced that as well. Funny thing however, is that I connected it today to check if anything new had come up (since I'm only getting 10.8km/l on the freeway!!! doing 120km/h) only to get three error messages, telling me again that there is no signal from sensor 2, and sensor one is returning non-sensible information, the other being P1173 on Self Adaptation Additive parameters TRA Bank 1.
Both being brand new, I tested for continuity to the ecu, and all seems fine? So what do you think is going on here?
