Hi All,

I just put my OBD 2 autoscanner on to my 2005 955I. I got a code PO135 and it also said O2 sensor heater circuit malfunction. Bank 1 Sensor 1. does anyone know what this means. The bike runs good. Also thanks to the person that posted you can use a auto scanner.

Thanks, Jeff

That is either open or short Lamda sensor (O2 sensor) - check wiring between ECM and the sensor itself - make sure exhaust has not burned through cable.
If wiring all checks out, replace O2 sensor.
