I have an i 02 sensor voltage low fault bank one

Is there any other causes except the sensor?

If it is the sensor does anyone know where it’s located on a Cuna gtd 2.0 2014

Many thanks

Thanks 🙏 if I go for a long run the light seems to stay off for a few days

I assumed bank 1 is by the dpf and there are no leaks there now would leaks further down the line affect it

You only have 1 bank on a 4 cylinder (1 exhaust manifold). P0131 will be either wiring or sensor. First check the wiring to the Lambda sensor, if it is good replace the sensor. This video will show you where it is
