hey all,

I recently got a P1198 on my 1999 D1. I've tried looking up the code and it's not listed. Anyone have any info on this code and how to fix it?

Thanks!

I had that pop up, and another related code, when I forgot to reconnect the fuel rail temp sensor after gasket service. I cleared the codes and the problem never reoccurred. Although, it could be O2 related(?).

Ok, got rid of that code by replacing both downstream O2 sensors today! Now, i have P1193. Any ideas on how to trouble shoot this one? It's an open or shorted heater circuit.

go back and check the connectors first to see if they are making good contact....then check the wire harness to see if there is a broken or shorted wire to the downstream sensors
