I bought a 2004 BMW 330ci 2 dr convertible last summer. Stored it for the winter. Love the Bimmer and lots of fun to drive. Wishing I did this long before now.
I had a engine light come on. OBD2 gave me an error code P2240. I changed the pre-cat oxygen sensors. Also had a leaking valve cover gasket so I changed it along with new plugs and ignition coils.
Cleared all the codes and went for a test drive. Runs great. But, I got an engine light on the test drive and the code is P2234, 02 sensor signal circuit shorted to heater circuit Bank 2 Sensor 1. Like I said both pre-cat oxygen sensors are new (NGK's).
Any help would be greatly appreciated.
Thanks,
Doug
