Could anyone please offer any help as to what I need to change with code P149B ok my 1.6 diesel 2014 CRV? Getting lots of different answers at the moment but none that seem to relate to a Honda.

 

Had a mare at the moment changing my fuel filter as the water light came on but appears it was the sensor so need to change that also lol.

 

But this P149B code has me stumped. Please help

The code translates as a faulty Evaporative Emission System Shutoff Valve 2 or the wiring associated with it

Would check the wiring first as may have been inadvertently disconnected while changing the fuel filter possibly?

Very interesting you say that.... As then I got under the car a connector was unplugged, but when I connected it nothing changed. Maybe the wiring is damaged 🤔

Maybe the fault code is still logged and needs erasing.
I would drop it back to the garage that fitted it clear the code
