TPMS Issue
randomly the other day I began to receive this message on my EVIC "TIRE SENSOR BAD / MISSING". It is displaying upon each start up since.
I had issues in the past and sensors have been replaced with new to me ones and all has been good for the past year. I attempted to retrain the sensors. And I am unable to retrain my right rear sensor. Is that a good sign that that's the one that is the issue? I have some more new to me sensors and could get installed. Would rather know for sure that's the one before playing games.
Thank you

Re: TPMS Issue
If you canīt retrain a sensor, than that sensor is bad.

Re: TPMS Issue
That's what I was thinking thank you Frank. But to add I gave it another attempt and was able to retrain all 4. And still receiving the error message. All tire pressures are flucuating on the EVIC. I am going to try the test I saw on And see if that helps me get any closure. I think I might just end up bucking up and buying a new set of 4, and being done with it. haha

Re: TPMS Issue
You don't have the spare tire sensor?

Re: TPMS Issue
nope. I just had a steel wheel for the spare from the factory. I believe they did away with the spare sensor before my model year. The wheels I have now I have a full spare in the spare area, but definitely no sensor in it.

Re: TPMS Issue
Its maybe the same test you had found, but this is from the jeep manual:

NOTE: The DRB IIIT Scan Tool can be used to select
a four or five tire pressure monitoring system.
The following test can be used to verify two functions.
One, that the tire pressure sensors are transmitting
properly and two, the EVIC module is
receiving these transmissions accordingly.
(1) Retrain the tire sensors (Refer to 22 - TIRES/
- STANDARD PROCEDURE). The tire sensors
must be retrained in order to set the proper transmitting
time cycle (twice a minute), failure to retrain
the sensors will cause a much slower transmitting
time cycle (once a minute).
(2) Using the STEP button on the overhead console,
scroll to the blank display, then press the
RESET button for five seconds, a beep will sound
indicating the start of this test. The vehicle icon and
transmission counters will now be displayed, (same
display as individual tire pressure except counters
replace tire pressure values).
(3) Upon entering the test mode, the EVIC will
clear the sensor counter and each time a sensor signal
for a road tire is received, the EVIC will update
the counter value (vehicle must be driven at 25 mph
to transmit). The counter values should all read close
to the same value (ą 5), except for the spare tire
counter. If any of the road tires display a difference
of more than five, this is a sign of a problem. Replace
the appropriate tire sensor and retest the system.
This test will continue until any of the overhead console
buttons are pressed or the ignition is turned off.
NOTE: Pressing the RESET button during the test
will sound a beep and reset all the counter values
back to zero.

Re: TPMS Issue
yep that's the test I did. And all the numbers increase and are within 1 from the same value. hmmm
