Tire pressure sensor calibration
Every one of my tire pressure sensors is wrong. I checked with two different gages. They are all reading 3psi lower than they should. Is there a way to calibrate them? I have done the reset to stop the warning, just find it annoying that they are all off.
Cheers!

If all wheels are 3psi low, I don't think it will give a warning. (If pressures were reset when 3psi was low) You should check for error codes. The batteries may be dead. It happened to me before in Infinity.

When the overnight temps here dropped super low it gave the warning, so I filled them with my own compressor. With all the tires filled properly the display on the dash showed 3 under on all four tires. All four batteries bad at the same time is a possibility. Any way to make the current value the correct value?

(I'm not saying that the battery in its 4 sensors is dead, so it shows low psi. In Infiniti, the battery of the sensors was low and sometimes when it could not receive data from the sensor, the vehicle would flash a tire warning.
When you look at the fault codes, the sensor battery low warning appears.)
