Hello everyone,

My engine light came on a couple of weeks ago and I went down to autozone an they put the engine light machine on for me to see what it was. Their machine came out with troubleshooting code P1188 & P1189.. So I went on the net a did a search to see what that meant and I found out that it has something to do with the "Fuel Tempature Sensor B Circuit High Input" for the P1188 code. As for the P1189 it said "Fuel Tempature Sensor B Circuit Intermittet".

Does Anyone know exactly what that means and what needs to be changed here in this scenario?

Thanks!

Good question Bodo61.. I'm still trying to figure out my whole car. Lol, I bought the car without knowing much about BMW's, just now I'm getting to know a bit more about BMW engines. Well, so far I know that I have a E46 pre-facelift which is a 1999 E46 328i. How can I look up all my engine info, etc..? Also can I check for a vacuum leak or check with a mechanic?

Thanks for the reply!

The better known term although not realy the same is SHORT TERM and LONG TERM fuel trim
Ok, I did a quick search on the net and found this page which explains fuel trim pretty good, I think! Lol at least I learned a bit about all of this fuel stuff. I also did a searched on your DIY and found the diagram, not sure if I'm going to try it out(don't want to f* anything up), but this definitely pointed me to the right direction!

Thanks!
