Tire Pressure Sensor Readings

My DIC states 33psi in tires and OnStar has set alarm that air pressure too low. Using 2 different gauges, they read 3-4psi higher than tire pressure sensor on DIC. Anyone seen this in their Camaros? Actual tire psi reading 304 psi higher than DIC pressure sensor reading.

Depends on what the tire temp is Cold tires and Hot tires are off by 2 to 4 PSI

also it dont read "all" the time just takes snap shots so unless you reset it so it learns again it will say the last time it took a snap shot of the PSI

I would recalibrate your TPMS sensors. Your tires should be at 36 psi cold. So you'd want to check the pressure before you drive.
