2001 Buick Lesabre Repair Question
2001 Buick Lesabre Tire Pressure Low Light
I recently purchased a used 01 Buick LeSabre. The first few days I had it, a message often appeared that stated my Tire Pressure was low. I checked all my tire pressures and I filled them up, but it still remained.
Then I had my car fixed for leaking shocks in the back, and the error message went away for 2 months. Now it is back, and I am not sure whether the problem is from leaking shocks, or if the sensor is bad or being deceived. I also have noticed a slight squeking noise from my brakes every once in a while, this leads me to believe that the shocks are leaking on my brakes some.
How can I tell if my shocks are still leaking? Could leaking shocks cause a sensor to fail?
Your owners manual should have some info on the tire pressure monitor.
My info shows that is an indirect system, it works through the abs system. The rpms on a low tire is a little different than the other tires. This type system won't work, unless the vehicle is moving. It won't tell you which tire has a problem.
Some bulletins I've seen, says to use the tire pressure rating on the driver door sticker not the spec on the tire.
Are there any abs codes? I don't know if a faulty shock would cause this problem?
I just wanted to add, anytime you change air pressure, have a tire worked on, or rotate the tires. You need to reset the monitor system. That's what the owners manual says. The manual will tell you how to reset the monitor.
