: tpms problem

10-04-12, 11:31 PM
Hey guys, every time I drive my car for about 10 miles I get a message saying "tire service monitor " or something like that, and after that message appears I noticed that my LF tire will stop reading psi's. But after I drive another 10 miles or so the tire pressure light will turn off and my LF will start reading psi's again. Can someone tell me what's wrong?

There is likely a faulty sensor in that wheel, although there are a few possibilities. Codes would also help. If the car travels greater than 40km/hour for at least two minutes, but doesn't receive a signal for in excess of 18 minutes, you will see this message. There are also other faults that can cause this.

Every well equipped tire shop should have a TPMS tester and analyzer like my Kent-Moore J46079 that will test both the TPMS sensors and the car's receiving system. The "dirt-floor" establishments are unlikely to be able to do much beyond throw parts at it.
