I used to have code p0340 that comes on once in a while for several months. I just clear the codes and no issues. I changed the camshaft sensor months ago but occasionally p0340 comes up. Now I get P0120 with and EML light is on with a lot of issues poor drive-ability thanks for your help. Did a lot of work on car.

Hello,

That code is for the TPS sensor which needs to be checked or replaced. Look at the electrical connector because they can become corroded. Here are the instructions and diagrams to help you change it out. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Hi,

I see the code P0120, but I need to know the model year and engine size. Also, confirm it is a 323i for me.

Take care,

joe
