M157/M278 Wire Harness Question - O2 Sensor related
Needing some help!!! Does anyone know on the M157/M278 motors, are they any connections in between the ECU connector and the O2 Plug connectors or is it a straight connection between the devices without any other connectors/connections? Trying to hunt down an electrical gremlin and thinking it could be related to a connector I can't see/find. Any help is appreciated!!!

MBWorld Fanatic!
Wiring schematic FTW here tbh.
However at a guess, it'll be ECU > main harness > sub-harness > Lambda
But my guess is useless in this case because you need to know for sure. What code is showing? P0036?

Thanks for the reply, were you posting a link to wiring schematic? If so it’s no there, I’m sure it will help so if u can post that would be great! It varies over time, p2198, p0036 p0157.
