I only have a code when the engine is less than 120F and the datastream says its 250F setting code 14. The code doesn't set after its warm. $8B as far as i know uses the same temp sensor as $0E (or is it $OE). The same part number "standard ignition, TX3" comes up. The sensors, all 4, 2 brands, have 3000 ohms at 70F and about 200 ohms at 220F with no jump in ohms at 120F. This sensor worked fine with code59 but not when i use $8B also works fine in my $0E 7.4l C3500 and this sensor is the only one that comes up when searching the most common ecms talked about here. It very well could be the wrong sensor, I just haven't found another option.
