Hi I have 2008 3.7L The tire pressure light is ON although the pressure is correct all 5 tires. How do I know which sensor of the 5 is failing ? Can an OBD scanner can help ? tnx Ilan

I'm a new owner of a 11 Nitro. Love the vehicle so far, but would like to replace a bent alloy wheel. Are the pressure sensors able to be reinstalled onto a new wheel? I know Chrysler makes some that are a one time installation.
