Help with the Tire Pressure Sensors Please

[TM888]

Like a few other people, I’m having a tire pressure issue now that the cooler weather is upon us. Left rear is down 5psi and I get a warning. I have an hour commute, so the pressures go back up, but not enough to turn off the warning. (I run my pressures at 42psi (hot) so the left rear is at 37psi.) I topped the left rear up last night using a digital gauge and this morning it was down exactly 5 again. Is it possible to have a slow leak that needs more than 35psi to force air out or could it be a sensor issue? Thoughts?

Try checking the tire pressure using a manual tire pressure checker. that would answer your question on if the sensor is the issue. If it isn't the sensor, it sounds like you have a small leak somewhere. You can take the tires off and check to see if there is a leak somewhere by spraying soap and water misture to see where the tire is bubbling or take it to a mechanic to get it check/repaired.

Thanks, but finally found a nail unfortunately. Sigh. First a windshield chip and now this. I might be jinxed!

I've experienced both of what you went through so feel your pain and only had the car for 4 months.
