I have 35psi in my tires. I have checked this with 3 different tire gauges. My TPS read 31-32 psi. Can they be recalibrated? If I get 35 on the sensors I'm at around 39psi in the tires.

 

They can't be recalibrated. But they should be a whole lot more accurate than ±4 psi.
What kind of gauges did you measure it with? If you used some of those cheap pencil or dial gauges, they could easily all be off. You need to get a high quality dial gauge to check the tire pressures.

If you feel the TPS sensors are off, take it back to the dealer as I'm sure you're still under warranty.

 

Thanks DavesZ,

I used a pretty good gauge that I,v had for years. I realize that doesn't mean much but seems all three gauges read the same so I thought they couldn't all be off. I'll purchase a digital one and give it a try. Thanks for the help.
