Hopefully you have code cleared up by know. If not I would check for continuous 5 volt signal to right header sensor. Then I would check for volt signal out to run somewhere between .5 and 4.5 volts from full lift to full lower. I believe there is more complete trouble shooting list on that error code operators manual but if not let use know. There is a constant that you would enter into tack module for the particular tire you have. This can vary some between tire manufature and a few other things so it is just a close estimate.
