I have an OBD II Ford vehicle and some of the generic data is reading 0 when there should be a value (O2 sensors, or vehicle speed for example). What is the problem and what can I do?
Some OBD II Ford vehicles, even though they support a generic parameter, will never send any data other than zero. However, the Ford Enhanced Parameter signal set typically does include enhanced parameter data for the non-valid generic data. Also note, some Ford vehicles will start sending valid O2 data once the vehicle is warmed up. Note: the Generic Parameters are included in the All Parameters group. To find the Ford Enhanced O2 parameters, sort on the parameter grid by description by clicking on the word Description at the top of the grid, and then page down to the parameters that start with B1, B2, and Bank 1 and Bank 2. These are the Ford Enhanced parameters and will properly show the O2 values.
