: Tire pressure sensor?

07-01-08, 12:44 AM
I've been having a little trouble with my passenger front. It will go from 30 up to 50 then down to zero. It's a drastic jump, not gradual. Do I need to get a new sensor or is there something else that could be causing this.

You don't provide much information, but, assuming that the other three TPSs work correctly, I would say that you need a new TPS. I would try reprogramming the TPSs first, then, if that doesn't correct the problem, get a new TPS for that position.

Unless the vehicle is under warranty, replacement of a TPS requires a fair amount of time and money (a new TPS is $70-$80). Remove wheel, remove tire, remove old TPS, reverse procedure and rebalance if necessary. After wheel is reinstalled, reprogram the TPM system. If you don't do the work yourself, there is, of course, a labor charge added to the parts cost.
