TPMS malfunction?

[zhliu]

I was driving on a bumpy road and the TPMS lit up. One of the pressure readings showed "**". But when I checked the tire with a pressure meter, everything looked fine. Could this be a malfunction of TPMS? If the senor in the tire is broken, is it replaceable in the dealership or from a general auto part store? Thanks.

The TPMS sensor in that wheel is probably broken if it only shows stars. Keep in mind that the sensors show up on the screen in the order they are registered with the on board computer. It's not like the front left will show up on the top slot, front right on the second slot, etc.

What you're probably going to need to do go down to either a tire shop or the dealership to first identify which sensor is having an issue. Then you'll have to get a new/used part, remove the rim from your MO, remove the tire, remove the old sensor, install the new/used sensor with a TPMS seal kit, remount the tire, rebalance the tire, then reinstall the rim on your MO. Finally after all that work is done, you'll need to have the sensors cleared from the TPMS computer's memory and then reregister them.

I think that the only way to actually register the TPMS sensors is to use the Consult-II tool that is available only at the Nissan dealerships.

Sorry man...this looks like it could be expensive.
