Take a reading on the left front and see if it's close to 32 (remember to do this in the morning before driving it, aka a "cold" reading). If it's 32, then mystery solved as to why only the right front sensor shows -4.

PS. Don't be upset with your Dad. He's just trying to help his favorite daughter. However, a word of advise. DON'T let your Dad add any fluids (antifreeze, pwr steering, oil, etc) to your car unless he's a Porsche guy. These cars take special fluids and adding ordinary fluids will damage your car. Most people don't know Porsches require special fluids, so unless he knows Porsches he may think it's OK to top off with what he has in the garage. That will be a costly mistake. Might want to casually mention this to him now before he tries to help you out without telling you. It will be too late then to have that conversation.
