Hey guys, so i've been dealing with this engine light for a couple of months now and cant seem to figure it out.
The code is P0140 (Bank 1 Sensor 2 after cat) which indicated "oxygen sensor, no activity detected" meaning the 02 sensor is showing ZERO activity with no fluctuation of power at all. Yes I have changed it out twice with Bosch kind thinking it would be the 02 sensor but this was not the case.
When I plug in my chinese BMW scanner the Oxygen sensor is completely dead showing "0" volts. All other sensors are working fine.
I've also: Inspected the Disa valve, cleaned MAF, inspect rubber boots, vacuum hoses, plugs and I still cant get this 02 sensor to come alive!
What are your thoughts??
All help would be appreciated.
