I am starting to see some false readings on a tire pressure sensor. My
C5 is a 2001 and I have replaced the tires three times in 60K and not
replaced the TPS units. How long do these little devils last before
they are completely toast? I have one that is questionable and three
still accurate, maybe. I am running Goodyear EMTs and managed to drive
the left front for two days completely flat. No indication on the
display, it showed 32 PSI, the handling went in the dumper and that was
my first clue.
Like people some die before their time but they should go 10 years.
Make sure you get the one used for the '01, they were a new design
that year. Try http://www.revolutionsupply.com/TPMS/AppGuide.aspx
$47.68, they have been a good supplier for me.
Easy to retrain for position with a good sized magnet.
With the key on, engine off, press both the lock and unlock buttons on
the key fob. A horn chirp within 10 seconds indicates the TPMS
receiver is in the programming mode. Place the magnet over the left
front valve stem until the horn chirps. This forces the LF pressure
sensor to transmit its code to the main module. Repeat the same
procedure for the right front, right rear and left rear sensors in
this order. Verify all four pressure readings are displayed on the
driver information center. Or, press the dic option button until
display is blank.
Hold dic reset button for 3 sec.
Press dic options button again, till the TIRE TRAINING msg appears.
Press dic reset button till the LEARN L FRONT TIRE msg appears.
Put magnet tool on the left front valve.
The horn will sound indicating LF pressure sensor is programmed.
procedure on tires as follows:
I ordered four new units, we will see how Discount feels about the
install process. I have a big magnet that really does the trick on
resets, just the LF has finally given up true readings...Thanks for the
insight to the TPS units.
